Transitivity
From UNLwiki
				Transitivity is a category that indicates the number of objects a verb requires or takes in a given instance.
Natural language
In the UNLarium framework, transitivity may assume the following values:
{{#tree:id=nl_TRA|openlevels=0|root=Transitivity (TRA)|
- no transitivity (NTRA): copula and linking verbs
 - transitive (TST): has object
- direct monotransitive (TSTD): one direct object
 - indirect monotransitive (TSTI): one indirect object
 - ditransitive (TST2): one direct object and one indirect object
 - tritransitive (TST3): three objects
 
 - intransitive (NTST): no object
- unergative (NERG): the subject is the agent
 - unaccusative (NACC): the subject is not the agent
 
 
}}
- Objects are to be considered elliptical (hidden) in verbal constructions if they can be inferred from the context.
 - I read all the afternoon = I read (something) all the afternoon = direct monotransitive (TSTD)
 - John kisses well = John kisses (someone) well = direct monotransitive (TSTD)
 - John buys (and Peter sells) = John buys (something) = direct monotransitive (TSTD)
 
- Different transitivity values mean different senses
 - The same verb may have different transitivity values, but only when associated to different UWs:
- John lives in Paris = intransitive (NTST) (live = reside)
 - John lives a nightmare = direct monotransitive (TSTD) (live = experience)
 
 
- Complements (essential) are not to be confounded with adjuncts (accidental)
 - John bought a car for Mary = direct monotransitive (TSTD) and not ditransitive (TST2), because "for Mary" is not a complement, but an adjunct of the verb "to buy"
 - John gave a car to Mary = ditransitive (TST2), because both "a car" and "to Mary" are complements of the verb "to give".
 
- Copula is to be considered without transitivity (NTRA)
 
- Subject and object complements are not to be represented as part of the transitivity of the verb
 - You make me nervous = You make [me become nervous] = direct monotransitive (TSTD) and not ditransitive
 - I considered him to be an excellent choice = I considered [that he was an excellent choice] = direct monotransitive (TST) and not ditransitive
 
- Transitivity is a property of the verb and not of the whole multi-word expression.
 - to make love = to make = direct monotransitive (TSTD) and not intransitive
 - to kill oneself = to kill = direct monotransitive (TSTD) and not intransitive
 
Examples
- English
- unergative (NERG) = run (John ran)
 - unaccusative (NACC) = fall (John fell)
 - direct monotransitive (TSTD) = kiss (John kissed Jane)
 - indirect monotransitive (TSTI) = depend (John depends on Jane)
 - ditransitive (TST2) = give (John gave Jane an apple)
 - tritransitive (TST3) = trade (John traded Jane an apple for an orange)
