acl: clausal modifier of noun

acl is used for dependent finite and non-finite clauses that modify a nominal (either a noun or a pronoun). The head of the acl relation is the noun/pronoun that is modified, and the dependent is the head of the clause that modifies the noun/pronoun: it can be the verb itself or an adjective part of a verbal predicate.

acl is used in the following cases:

Commossa/VERB[Tense:Past|VerbForm=Part] , Fiona/PROPN May/PROPN ha/AUX parlato/VERB
acl(Fiona, Commossa)
nsubj(parlato, Fiona)
name(Fiona, May)
