IDENTIF. * (locative) - + + - - - + + Heuristic consequences The matrix makes possible to decide to what class a single instance of the corpus belongs by analyzing the semantic features of the complement (equivalent and positive features) The classification of the uses in the corpus allows extracting from the data significant grammatical features, in order to properly describe the verbal variation of “essere” General structure of the taxonomy (revised) Percentages of verbal uses Quantitative results Reduced percentage of marked variation marked variation is estimated to cover more than 50% of the high frequency action verbs (Panunzi & Moneglia 2004) High percentage of identificative uses consistency of such a use Quantitative prominence of copular uses with respect to predicative/locative ones COMPARISON WITH GENERATIVE GRAMMAR Copular clauses taxonomy in Generative Grammar Main distinction among two different types of copular sentences (Akmajan 1970) predicational clauses, in which the post-copular NP is not referential, and it constitutes a proper predicate Carl is bald specificational clauses, in which the post-copular NP is properly referential, referential and it specifies an individual entity my best friend is Carl Higgins referential taxonomy (simplified) NP1 NP2 predicational Referential Predicational specificational Superscriptional Specificational In the proposed taxonomy, a specific class is then contituted by identity statements (“The Slim” is Carl), that roughly corresponds to the ones discussed by Frege; in this case, both the NPs have a referential value identity statement Referential Referential Criticism Ad hoc referential values es. superscriptional The taxonomy criteria take into account both the referential value of the subject and the one of the complement referential type of the subject has no correspondence to the semantic value of the predicate Inverse copular sentences These proposal led to the hypotesis that specificational structures are copular clauses in which the NP1 (in subject position) is the actual predicate, and the NP2 (in complement position) is the actual subject: [John]subj is [the teacher]pred [the teacher]pred is [John]subj In brief, specificational clauses are considered as inverse copular sentences (Blom & Daalder 1977; Verheudg 1990; Moro 1997, Mikkelsen 2005) Copular clauses: shared deep structure (Heggie 1988) Predicational clauses: shallow structure Specificational clauses: shallow structure (Moro 1997) Theoretical consequences Counter-evidence against the common assumption that the relation between the NP and the VP that are bound in the clause structure determines the grammatical functions of Subject and Predicate (Moro) it deals with the general theory of clause syntax Further interpretations place these facts at the level of the information structure (cfr. Mikkelsen 2005) Heuristic consequences Crucial role of the NP in the “subject” position in determining the type of the copular clause This perspective gets rid of the identified semantic distintions Identificational uses Predicative-locative uses VARIATION STRUCTURE Lines of variation Type of use Semantic value of essere Line of variation Copular Property attribution (extensional relation) Type of the property Identificative Identificative relation between different referential expressions (intensional relation) ontological class of the entity to which the expressions refer Predicative Locative relation (locative basis) (relazione tematica) cognitive domain within which the relation between the theme and the object of reference is set up Predicative uses (locative basis) Spatial localization *IAS: qui / siamo alla foce del fiume // [here / we are at the mouth of the river] Temporal localization *NON: sì / la [/] la fiera / l' è il secondo martedì di luglio // [yes / the fair is on the second tuesday of July] Possess relation (as localization) *LID: questi / erano della mamma // [these ones / belonged to my mother] Other uses (corpus-driven) Benefactive relation *ANT: è per la gente che si deve divertire // [It is for the people who want to have fun //] Causative relation *CLA: non so se è per questione di soldi / di interessi / per questione di culture forse diverse // [I don’t know if it is because of money / of profit / because of different cultures //] “Co-localizzation”: *ROS: eravamo sempre con Adriana / e il suo bambino // [we always were with Adriana and her child] Sematic variation of copular uses PROPERTY TYPE EXAMPLE Quality 'un è mica brutto // [he isn’t ugly at all] Class [...] gl'era un falegname / gl'era un artigiano // [he was a joiner / he was a craftsman ] Quantity gli arcani minori e quelli maggiori / sono 52 / [the minor arcana and the major ones / are 52] Measure era 95 chili / quando ci si sposò / i mi marito // [my husband was 95 kilos / when we married] Comparison mio fratello è così // [my brother is this way] Judgment è giusto e corretto / che parli l’Istituto Superiore di Sanità / […] // [it is right and correct / that the ISS…] Internal variation of copular uses Different uses correspond to a single and primary semantic core Internal line of variation: type of the property assigned by the copular relation Identificative uses subj – essere – NP[+definite] *ANN: che lui è il presidente del Sunia // [that he is the president of Sunia] *ZIA: l' abbraccia gli fa / Attilio / sono io il fiorentino // [he hugs him he say / Attilio / I am the Florentine] *CUC: il mercato è questo // [the market is this] *VAL: cioè / la mia sede definitiva / è Piombino // [I mean / my final location / is Piombino] Ontological types of the entities in equivalence relation Places *LIA: e qui è San_Gottardo / eh // [and here is San Gottardo / eh] Times *MAX: perché qui è il ‘59 // [because it was 1959] Events *ELA: che / era la volta che tu cantavi / … [that / it was the time that you were singing / …] Equivalence between entities of the Event ontological level Nominalizations *GUI: l' occasione è stata che / […] sono andato a fare i' camionista // [the occasion was that / […] I became a truck driver] Pseudo-clefts *ANT: quello che non accetti / è che ti giudichi un deficiente // [what you don’t accept / is that an idiot judges you] *LOR: la cosa che ha fatto incazzare è stata questa // [the thing that made me angry was this one] CONCLUSIONS Semantic classification of corpus instances Possibility to produce a corpus-based classification of the semantic values of the verb essere: extensional relation (copula) intensional relation (identification) thematic relation (localization) Predictability of semantic values The different semantic values of the verb essere are predictable on the basis of equivalent and positive features of the complement: copular “essere”: lack of referentiality in the complement identificative “essere”: referentiality of the complement, without association with a thematic role predicative-locative “essere”: referentiality of the complement, in association with an explicit thematic role Taxonomy consistency Descriptive criterion the variation perspective assures the identification of types which mirror real uses Consistency of the taxonomy productivity of the classes and quantitative (external) consistency of the classification internal consistency of the classes of variation, identified by specific lines of variation Comparison with Generative Grammar taxonomy Lack of semantic representation autonomy of each semantic field of variation Lack of observational adequacy it makes impossible to explain the lines of variation found by means of the corpus driven analysis References Akmajan, A. 1970.
