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
 - intransitive (NTST): no object
- unergative (NERG): the subject is the agent
 - unaccusative (NACC): the subject is not the agent
 
 - direct monotransitive (TST): one direct object
 - indirect monotransitive (ITST): one indirect object
 - ditransitive (DTST): one direct object and one indirect object
 - tritransitive (TTST): three objects

- Elliptical objects
 - In the UNLarium framework, objects are to be considered elliptical (hidden) in verbal constructions if they can be inferred from the context.
- I read the book = I read all the afternoon = direct monotransitive (TST) (no significant semantic change)
 - John kissed Mary = John kisses well = direct monotransitive (TST) (no significant semantic change)
 - John bought a car = John buys (and Peter sells) = direct monotransitive (TST) (no significant semantic change)
 
 
- Different transitivity values mean different senses
 - In the UNLarium framework, 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 (TST) (live = experience)
 
 
- Objects (essential) are not to be confounded with adjuncts (accidental)
 - John bought a car to Mary = direct monotransitive (TST) and not ditransitive (DTST)
 
Examples
- English
- unergative (NERG) = run (John ran)
 - unaccusative (NACC) = fall (John fell)
 - direct monotransitive (TST) = kiss (John kissed Jane)
 - indirect monotransitive (ITST) = depend (John depend on Jane)
 - ditransitive (DTST) = give (John gave Jane an apple)
 - tritransitive (TTST) = trade (John traded Jane an apple for an orange)
