Ter / Haver-Constructions and Verbal Agreement

The aim of this paper is twofold: (i) to analyze the use of the verbs ter and haver in the history of Portuguese and, more specifically, in a recent stage of Brazilian Portuguese, in which the possessive ter is used as an existential verb; and (ii) to discuss some properties involving ter and haver in possessive and existential domains, in both European and Brazilian Portuguese, pointing to the possibility of verbal agreement with ter/haver-existential constructions. Exploring results from previous analyses it is shown that some properties of existential constructions, in contemporary Brazilian Portuguese, can derive from changes involving subject position, related to the weakening of flectional paradigm.


Introduction
Throughout the recorded history of Portuguese language, ter (<tenere) and haver (<habere) may be considered verbs with broad functionality.Their multiple functions range from main verb, indicating (1) possession and/or (2) existence to (3) auxiliary indicating time, mood, and aspect.They may even occur as (4) "light" or functional verbs that transfer the predication to their internal argument.
(1) Ele tem muitos carros na garagem has "He has many cars in the garage" J Journal of P Portuguese L Linguistics, 12-2 (2013), 187-208   ISSN 1645-4537  (2) Há / Tem muitos carros na garagem there are / have "There are many cars in the garage" (3) Ele tinha / havia comprado muitos carros had bought "He had bought many cars" (4) Ele tem tempo para fazer o trabalho has time "He has time to do the work" In this paper we will focus on the ongoing flow of change, pointing out to the historical, structural and social constraints involved in the competition between ter and haver.We will emphasize (i) the role of the reduction of verbal paradigm on the emergence of ter-existential, in Brazilian Portuguese, as well as (ii) the possibility of agreement between the existential verb and its complement in constructions such as tinham/haviam pessoas na festa ("had/there were persons at the party"), considered incorrect by normative grammatical tradition.
Our results are based on qualitative and quantitative sociolinguistic variation analyses in real time and in apparent time.The written sample (200 possessive clauses with ter and haver in Medieval Portuguese), spanning the 13 th to the 16 th century, were extracted from the Corpus Informatizado do Português Medieval (CIPM).For the facts in contemporary European and Brazilian Portuguese, we analyzed a sample of 1.528 existential clauses, referred to in previous papers by Callou & Avelar (2002, 2003and 2006).The spoken data, stratified by age and gender, were taken from informal interviews of University graduates (standard dialect) from Rio de Janeiro (NURC sample) and Lisbon conducted in the 1970's and 90's (20 th century) for a trend study (Labov, 1994).More recently, a new sample of standard speech (around 1000 existential clauses), recorded in some areas of Rio de Janeiro (BP-Copacabana/Botafogo) and Lisbon/Oeiras (EP) at the beginning of the 21 th century, has been added.

An overview of the past
Since the earliest documents in Portuguese (Mattos & Silva, 1989/1996/ 1997) and Spanish (Camareno, 1997, apud Viotti, 1999), there is a tendency to use ter as a verb of possession and, by the mid-16 th century, ter had displaced haver from this semantic domain.On the other hand, haver replaced ser ("to be") as the main existential verb, and the frequency of the use of ter in existential clauses increased gradually over time (Figure 1).This change may also be traced back to the 16 th century, the same period when haver no longer indicated possession, except in specific contexts.The structural overlapping of these verbs seems to have its roots in developments that took place much earlier in Latin.
Figure 1 -Use of ter/haver-existential clauses in written texts in the history of Portuguese Many authors class existential and locative sentences together.Lyons (1979) has observed that in almost all modern languages possessive and existential clauses may be considered to be syntactically derived -both synchronically and diachronically -from locative constructions.Guéron (1986( , apud Franchi et alii, 1998) ) justifies this hypothesis based on the use of the same verb, avoir, in existential and possessive sentences in French.The same is true for Brazilian Portuguese, where the use of ter in the third-person singular gives rise to an existential expression.
Observing the history of the verb ter in Brazilian Portuguese, Viotti (1999) concludes that all sentences with this verb -regardless of semantic domain -have the same syntactic origin.Franchi et alii, based on the properties observed in the analysis of a corpus of spoken Brazilian Portuguese, say that "existential sentences belong to a class of constructions called impersonal constructions".Many linguists also mention that the noun phrase following the verb is usually indefinite -the so-called definiteness effect noted by Milsark (1979).
As for the facts regarding the verb haver in Medieval Portuguese, the causes for reanalysis of this verb as an existential item, with its losing the possessive interpretation, are not yet clear.In that period, both haver and ter occurred as possessive verbs, as can be seen in examples ( 5) and ( 6).
(5) Figure 2 shows the frequency of haver and ter in possessive contexts from the 13 th to the 16 th century.Note that there is stability until the 15 th century, the rates of haver and ter being, respectively, 72% and 28%.This scenario changes abruptly in the 16 th century, when the rate of ter rises to 90% and overtakes the rate of haver.From the 16 th century on, haver was completely removed from possessive contexts and acquired exclusively existential meaning, occurring in impersonal sentences like the ones exemplified in (7).It is significant that haver had occurred as an existential verb since the 13 th century, sharing this expression with the copular verb ser, as in (8).

An overview of the present
Nowadays, the use of ter-existential (as opposed to haver-existential) is predominant in contemporary spoken Brazilian Portuguese.Considering the two decades, the 70's and in the 90's, the results suggest change in progress (Figure 3).It has been assumed that certain syntactic, semantic and social factors are related to the variation between the two verbs.For spoken language (1528  1 shows this contrast and the increase in use of ter in the 90's, when the verb is in the perfect.The statistical results suggest that, in spoken language, the use of haver has almost become restricted to the past tense.For the semantic nature of the internal argument, the factors postulated were: animate (9 and 10), inanimate -concrete -(11 and 12), abstract (13 and 14), space -public place, district, region-(15 and 16), and event (17).The possessive verb ter "to have" replaces haver "to exist/there to be" even in elapsed-time expressions (18 to 20), but the two elapsed-time expressions reflect variation between two distinct structural patterns.
" There are three months ago I returned from Europe" Lit.: " There exist/have three months since I returned from Europe" (19) Já vive cá há uns anos (OEI A3H) there are "He has lived here for some years" (20) Tem mais ou menos um ano (OEI A3H) has "It has been about a year" Generally, when the internal argument is an "event", the verbs ter and haver have the meaning of "occur", "happen" or "take place", as in examples ( 21) to ( 23) and can be translated by "there is/are".In all contexts, the frequency of use of ter-existential sentences has increased over time.The great majority of cases that favor the use of haver refer to prototypical cases of the so-called "light" verbs, the object of which is neither definite nor referential, as in examples 24 to 26.The distribution patterns by age group are similar, but in the 90's there is a clear opposition between younger speakers, on the one hand, and adults and older speakers, on the other: the curve shows change in progress towards reduction in the use of haver-existential.Nowadays, it seems that the use of ter is less stigmatized in school, even in written language.Gender may also have a significant effect, mainly in the 70's (Figure 5).It seems that women led the process, since younger women show higher frequency in the 70's (80% female versus 46% male), the use of ter being almost categorical (98%) in the 90's, in both male and female speech.Parallel to Labov's reasoning (1994: 65) on the stratification of sound changes, we assume that in a change near completion, as in the last decade of the 20 th century, gender is neuter, while in a new and vigorous sound change, as in the 70's, gender is still a significant conditioning factor.

The emergence of possessive verbs in existential environments
As indicated in Avelar (2009a), the sentences exemplified in ( 27) are interpreted as a possessive construction in European Portuguese.By contrast, in out-of-the-blue contexts, a Brazilian Portuguese speaker interprets them as existential.To receive a possessive interpretation, in Brazilian Portuguese, it is necessary to project a possessor subject, as in (28).In European Portuguese, ter is rarely used in existential constructions, almost only haver: 'Há várias calças dentro do armário'.
have several pants inside of-the closet EP: "He/She has several pants inside the closet."BP: "There are several pants inside the closet."b.Tinha um documento na carteira.
had a document in-the wallet EP: "He/She had a document in the wallet."BP: "There was a document in the wallet."c.Tem dois computadores no escritório.
has two computers in-the office EP: "He/She has two computers in the office."BP: "There are two computers in the office."In a previous paper, Callou & Avelar (2000) suggested that a strong candidate for the trigger to the reanalysis of ter as an existential verb is the inflectional reduction of verbal paradigm in Brazilian Portuguese.As pointed in many studies (Duarte 1995;Tarallo 1996;Figueiredo Silva 1996;Galves 1996;Kato 2005; among others), this inflectional reduction had a drastic consequence in the use of referential null subjects: the contexts licensing referential null subject in Brazilian Portuguese became extremely restricted, as we can see in sentence (29a), 'Comprou um carro', corresponding to 'Bought a car'.In European Portuguese, this sentence can mean 'He/She has bought a car'.In Brazilian Portuguese, however, it would be necessary to fill the subject position, in order to yield an acceptable sentence, as we can see in (29b).
(EP: ok / BP: ok) he bought a car 'He has bought a car.' Returning to the possessive verb, it is almost impossible for a speaker of Brazilian Portuguese to interpret ter sentences with referential null subjects as it would be the case if these contexts were interpreted as possessive.For instance, in ter constructions, as in (30), European Portuguese grammar can license a null referential possessor: (30a) 'has a book' = 'He/She has a book'.But these same constructions are unacceptable in Brazilian Portuguese, because it is impossible for a Brazilian Portuguese speaker to license a null referential possessor in such contexts.
(EP: ok / BP: * ) had money "He/She had money." All studies dealing with the variation of ter and haver in Brazilian Portuguese (Cardoso 1986;Callou & Avelar 2000, 2003, 2006, Silva 2003; and others) conclude that ter is much more frequent in speech than haver.As illustrated in Figure 6, haver is largely preferred in formal written language, but its frequency is extremely low in spoken language, even among people with a high level of education.2013) show that there is a temporal parallelism that reinforces the hypothesis of a relation between the restrictions to the use of null subject in Brazilian Portuguese and the generalization of ter-existential: the existential use of ter began to appear at the end of the19 th century, and it is exactly in this period that the first signs of the null subject loss are detected in written documents (Duarte, 1995;Tarallo, 1996).As it is shown in previous analyses, there is no clear example of existential ter until 18th century in written documents in Brazil, but the frequency of ter, opposite to the frequency of haver in existential environments, reaches 22% in the second half of the 19 th century, as we can see in Figure (7).A study by Duarte (1995) reveals that, in this same period, the rate of null subjects corresponding to the third person began to decrease, going from 83% in 1845 to 55% in 1992, as in Figure ( 8).In this sense, the variation of ter and haver in Brazilian Portuguese may reflect a syntactic solution in the domain of the possessive-existential constructions to deal with the loss of referential null subject.It is important to notice that, in European Portuguese, some constructions with the verb ter can be analyzed as existential, even if we consider that this use was registered in a no-transparent environment, the so-called 'opaque' (Mattos e Silva, 1982) environment (examples 31 and 32).The examples were taken from young speakers (25 to 35 years old) with high level of education.It is not clear, however, whether these examples of ter-existential are the result of possessive constructions that, in a specific context, can receive an existential interpretation.

Generic pronouns in subject position in Brazilian Portuguese existential clauses
One possible consequence of the restriction to licensing null subjects on the configuration of existential constructions, in Brazilian Portuguese, is the increase of the frequency of use of ter-existential clauses with a generic pronoun (Avelar 2009b;Marins 2013;Duarte 2007), usually você ("you"), in subject position, as seen in examples (33) and ( 34).
(33) em Kioto, que era a antiga capital do Japão, você tem esses templos lado a lado com ...(90-012) "In Kyoto, which was the ancient capital of Japan, you have these temples, side by side with [...]" (34) a gente tem uma aglomeração de pessoas aqui na Tijuca (90-002) "we [=people] have a bunch of people here in Tijuca" "In Kyoto, which was the ancient capital of Japan, you have these temples, side by side with [...]" This usage increases in the 90's (Figure 9) and it has been explained within the general tendency towards the loss of the status of canonical pro--drop language (Duarte, 1995).As pointed out in Callou & Avelar 2002, the rate of 'você' in existential environments attains 21% among younger speakers.Note that it is impossible to insert 'você' when we use the verb haver, as we can see in (35).This contrast can be explained as constructions involving ter, even as an existential verb, retaining a subject position to be filled, while haver, an impersonal verb, has no position to receive a subject.In other words, the structural properties of the possessive ter, regarding acceptance of an external argument, were maintained in the existential version of this verb.
When haver lost its possessive status and became an existential verb in Medieval Portuguese, it usually occurred with the deictic locative pronoun hi as a subject (Said Ali 1964, Mattos & Silva 1997), as can be seen in sentences like (36).This property indicates that, even though haver has lost the ability to receive a subject in contemporary Portuguese, it did exhibit this property in its early stage as an existential verb.Although it is not clear why haver lost this property, the occurrence of a deictic locative pronoun as subject reveals that, in its first steps as an existential, this verb exhibited a property of its possessive version.
(36) a. Não ha i segredo (16 th century -presented in Said Ali 1964) not exist there secret "There is no secret."b. avya hi muytos mouros vezinhos acerca da cidade (Crônica de D. Afonso, Chapter II -14 th Century.Source: CIPM) were there many Moors neighbors around the city "There were many neighbor Moors around the city" c. ...que non aviay mouros nem judeus (13 th century -Presented in Mattos e Silva 1997: 262) that not were there Moors nor Jews d. con sua herdade que y ha e co suas pertijças (13 th century -Presented in Silva 1997: 262) with his heritage that is there and with his belongings

Verbal agreement
In this section, we focus on the possibility of agreement between the existential verb and the NP traditionally analyzed as its direct object.As a starting point, it is necessary to call attention to the structural contrast between possessive and existential versions of ter/haver, in the history of Portuguese: when haver and ter indicate 'possession' they behave as personal verbs and agree with its external argument --{-plural][-plural] and [+plural] [+plural]; when haver and ter indicate 'existence', they behave as an impersonal verb and do not check agreement.Traditional grammar points to the fact that the verb is invariant --does not accept number and person inflexions --and the post verbal argument, necessarily indefinite, is interpreted as an object.
One instance of variation to be examined is verbal agreement with ter/haver-existential constructions when the subsequent complement is [+plural].The case illustrated here (example 37) is so-called "object-verb" agreement.
(37) aí me lembrei que tinham duas senhoras (BP-COP B3H) had "Then I remembered there were two ladies" The phenomenon of verb-agreement in existential constructions is not restricted to Portuguese.It occurs in American Spanish, in standard speech, as registered by De Mello (1991).He points to the high frequency of use in Lima, La Paz, Caracas, San Juan de Porto Rico and Santiago do Chile, low frequency in Bogotá and Havana, and rare cases in Mexico City Buenos Aires.According to Montes Giraldo (1982), based on Colombian speech, it is sometimes considered a regular and usual form.
Like haver in Portuguese, haber in Spanish is considered the prototypical existential verb, but the verb-agreement phenomenon as in ( 38) and ( 39) has been studied in greater depth in Spanish than in Portuguese.In some areas of Spanish American countries, it is not uncommon for the verb haber to agree with its sole argument, as in ( 38) and ( 39).In other areas, verbal agreement is even considered the standard pattern.(39) En el frente agrario habían problemas adicionales.(Chile) "On the agrarian front there were additional problems" Some authors, including Bello (1847), Cuervo (1939) and Ureña (1940), have attested to the appearance of the phenomenon in Spain.Addressing the instability between subject and object -that is, interpretation of the argument as a subject or an object -these authors say that the complement of some impersonal verbs, such as haver, maintains a semantic relation with the verb equivalent to that of a non-active subject.They also mention that the NP that occurs with the impersonal verb haver displays some properties that distinguish it from the direct object of regular transitive verbs: (i) it cannot become passive; and (ii) the argument is necessarily indefinite, with partitive interpretation in most cases.Fontanella (1992) confirms that, in existential constructions, in contemporary American Spanish, the verb haber very often agrees with the direct object.
(40) hubieron...charlas (41) hayan causas Some authors say that, from a diachronic perspective, this phenomenon is the result of a slow ongoing change.Due to its original possessive value and action as an auxiliary, haber had always competed with tener.The use of existential haber has persisted since the 16 th century, and the construction is represented by the verb plus a noun phrase complement (V + NP) with no number agreement between the two elements.From the 18 th and 19 th century on, cases of haber-existential have been detected in which the verb agrees with the NP [+plural] (42).
In Bosque & Demonte's descriptive grammar (1999), it is possible to verify that the impersonal verb haber has been studied from different perspectives and that, although it should be only used in the third person singular, given that it is an impersonal verb, it may also occur in the third personal plural (42.10.1.4: 2770).
It is really the verb haber the one that occurs in the majority of constructions -so frequent as so much stigmatized -in which a plural noun, a direct complement, is seen as a subject and consequently triggers the plural form of the verb […] hubieron accidentes ("There were accidents") 2 .
In our 21 st century sample, in Brazilian Portuguese, no data were detected with the verb haver, only with ter (example 43).
(43) tinham duas concorrências "There were two submissions" The above authors refer to a stigmatized use, in Spanish, in the first person plural, as on example (44) and a similar example was recorded in contemporary European Portuguese, but, once again, only with the verb ter (45).
(44) Alli habíamos muchas personas en el cine (45) Temos exemplos de pessoas (OEI A3H) It is important to note that grammarians of the past have long interpreted the complement of haver as an external argument (a subject), consequently leading the verb to agree with the nominative form: [-plural]  third person singular and [+plural]  third person plural.Lack of agreement was considered a peculiarity of speech (idiotism).
Nowadays, agreement may be observed, especially in contexts where the speaker is in a formal situation and wishes to be well regarded; in political discourse, for instance.As haver is rarely used colloquially, when the speaker uses the plural form -as with ter-existential -it is immediately striking.Switching between the two uses -as a personal verb (indicating possession) or as an impersonal verb (indicating existence) -could be the reason for the possibility of inflection when the internal argument of the verb is [+plural], as noted by many grammarians and linguists.Diaz-Campos (2003) observed the behavior of the verb from a sociolinguistic perspective in two corpora of Caracas Spanish, one recorded in 1977 and another in 1979.All the constructions with com haver-2 The authors are responsible for the translations into English.
-existencial + plural noun phrase were analyzed, taking into account structural and social variables.He concluded that we are dealing with stable variation, although previous studies have detected a higher frequency of use among young speakers.The phenomenon has no social marker, but its relative weight reaches .50, in the middle-class group, in the 80's.The feature [+human] is important mainly when the NP is the discursive topic, which corroborates the interpretation of the NP as a subject and, for this reason, triggers verb agreement.As in Portuguese, pluralization is not recorded in the present tense of the indicative mood.
Many authors have attested to this variation of use [+singular] ~ [+plural] of the verb haver-examples (46) and ( 47) -and native speakers identify and stigmatize them.Nonetheless, although educated speakers consider the plural form a grammatical violation of the standard pattern, there is no detailed comparative analysis in Portuguese to establish the exact conditions in which it occurs.
(46) havia(m) muitos livros sobre a mesa (47) había(n) muchos libros sobre la mesa "There were many books on the table " One of our concerns is to observe this possibility of verbal agreement rather than to identify the moment at which traditional and prescriptive grammar fixed the obligatory impersonal use of haver-existential, as referred by Castro (2003:13) I do not know the exact circumstances in which it was inserted in Portuguese grammar the idea that haver meaning 'to exist' ' to have existence' is exclusively an impersonal verb, when many writers and many speakers think and act in another way.
As attested by modern prescriptive and descriptive grammars from both Brazil and Portugal, haver-existential is considered an impersonal verb; it consequently has no subject position and should be used only in the third person singular.
In ancient texts from the 1540's and 50's, there is already evidence (although rare) of the use of third person plural forms of ter --which are not mentioned in classic studies of historical syntax -and haver as an existential verb with agreement, a use referred to some centuries later (18 th ) by Said Ali as an innovation.
To Castro (2003), although prescriptive grammars base their rules on literary examples, and pluralization is attested in written and spoken varieties even among well-known writers, the third person plural form of the verb is rejected when haver is in the existential domain.He signals an example (op.cit.12) that is considered incorrect -houveram risadas ("there were laughs") -in order to show that it is not the writer, but the normative grammarian, who sets the standard pattern of use: the writer represents the pretext.
It happens that along with many other examples of houveram e haviam it can be found in the manuscript of the Tragédia da Rua das Flores, written by Eça de Queiroz.It will be in vain that we will look for it in any edition, as far as editors corrected the use of the writer in the name of normative grammar [...] Two 18 th -century grammars -Argote (1725) and Lobato (1770) -declare, in their chapters on agreement and "idiotisms" (Ch.V, pp.258-259), that the verb haver in existential constructions should be in the third person plural form when the NP is [+plural], a rule that runs counter to 20 th -century grammar.Argote's grammar reproduces a dialogue between Master and Disciple.
D. There are idiotisms in a verb's agreement with its nominative.M. Why? D. Because the verb haver in the third person does not agree in number with its nominative.M. Give an example.D. Há muitas flores nesse jardim ("there are many flowers in this garden").The verb haver is in the singular, and its nominative Flores ("flowers") is in the plural.
[...] Which is an Idiotism and very irregular Grammar.In Lobato's grammar, Lesson II (On a verb's agreement with its nominative), we can read: "It seems that the rule mentioned for the verb have is not observed when, based on language usage, a plural nominative is added to a third person singular, as when we say Ha muitos homens, que amão as ciencias ("There are many men who loves the sciences").[...]He explains that this is a case of Silepse, verb agreement being related to an implicit unexpressed nominative 'número' ("a number of ...") and, for that reason, the verb is in the third person singular.
Data from standard speech, extracted from www.letras.ufrj.br/nurc-rjand www.letras.ufrj.br/concordancia, in BP (Rio de Janeiro-Copacabana) and EP (Oeiras/Lisboa) were analyzed in order to confirm these points.Comparing these results to those of De Mello (1991), Bentivoglio (1992) and Diaz--Campos (2003), who studied several Spanish varieties, it can be concluded that the use of the third person plural form of haver is much less frequent in Portuguese, at least in the standard variety.
The analysis shows that, in standard speech, agreement of the verb with a plural internal argument is rare.First of all, the use of haver-existential in spoken language, as shown in Figure 6, is less common (13%) and only the tokens with a plural argument can be computed: of the 616 tokens from Rio de Janeiro (NURC samples), only 83 met the conditions and only two (less than 3%) were recorded with the third person plural form of the verb.
(53) com as Embaixadas que haviam então (RJ-inq.133/90) "with the Embassies that there were then" It should be observed that in one of the examples (53) the verb is in a relative clause and the preceding NP is more easily interpreted as a subject.No plural agreement was detected in spoken language in any of the 40 tokens of European Portuguese.
In the concordância data, in Brazilian Portuguese, use of ter-existential was predominant -86% frequency (342/396) -with haver occurring mostly in the past (example 54).
(54) mas houve um abandono nesse intervalo (COP B3H) "but there was neglect on that interval" On the other hand, no example of haver-existential in the third person plural was recorded in this sample.However, three examples (1%) were detected and only with with ter-existential, as in example (55).
(55) mas aí vou te contar... tinham dois guias na nossa excursão (COP C3H) "but then I will tell you... there were two guides on our excursion" In European Portuguese, only 6% (20/312) admit existential interpretation, as in examples ( 56) to (57), and verbal agreement does not occur with either haver or ter."and speaking about the problems -they are there ... and (they) want a bit of attention ... already had (there were) people that have told me"

Final remarks 3
To sum up, verbal agreement with existential verbs is a phenomenon that occurs not only in Portuguese (less frequently), but also in Spanish (where it is more frequent).This may be because, at least in Brazilian Portuguese, the impersonal verb haver has been replaced by ter, which usually allows inflection as a possessive or existential verb.In both languages, the plural form is blocked when the verb is in the present tense and is more likely to occur when the verb is in the past, in both indicative (houveram-tiveram/haviam--tinham) and subjunctive moods (houvessem-tivessem).These are verbal forms in which the difference between the singular and the plural is much more salient.Analysis shows that the use of the third person plural of haver/ter--existential constructions when the post-verbal argument -interpreted as either nominative or accusative -is [+plural] is rare.Nevertheless, it is very conspicuous, perhaps due to the high phonic salience of the forms.This paper has also shown that (i) there is a real-time change taking place (haver-existential ter-existential); (ii) age-grading seems to be involved in the process (in Brazilian Portuguese, younger speakers no longer use haver--existential sentences in speech, although this is not the case in European Portuguese); (iii) the use of haver-existential (78%) prevailed until the 19 th century; (iv) haver has become a typical verb of narrative, a modality of discourse that favors the use of the past tense; (v) the use of ter-elapsed time expressions, in standard dialect, is detected only in the 1990's sample and it must be asked whether we are not dealing with a strict variation here, because there are differences between the two types of constructions at the syntactical level; and, most importantly, (vi) the analysis reveals a crucial aspect of major changes in the history of Portuguese: the existential versions of ter and haver have inherited syntactic-semantic aspects of their possessive versions, comproving that an item can emerge into a new context without changing its essential selection properties.

), in both decades (the 70's and 90's), the multivariate analysis 1 shows that the most significant structural factors are the verbal tense and the semantic nature of the internal argument.Relevant social variables are age group and gender.Ter-existential sentences usually occur in the present tense, and haver in the past (perfect and imperfect).The Table
