nsubj: nominal subject

A nominal subject (nsubj) is a nominal which is the syntactic subject of a clause. The governor of this relation is typically a verb with an exceptions: when the verb is a copular verb, the nsubj relation is headed by the complement of the copular verb, which can be an adjective or a noun.

Ai balconi si affacciano donne/NOUN anziane.
nsubj(affacciano, donne)
Chi/PRON ha ucciso l'ingegner Reali?
nsubj(ucciso, Chi)
La situazione arbitrale è pessima/ADJ.
nsubj(pessima, situazione)
cop(pessima, è)
Questa ricchezza è tutta apparenza/NOUN.
nsubj(apparenza, ricchezza)
cop(apparenza, è)

The nsubj role is only applied to semantic arguments of a predicate. When there is an empty argument in a grammatical subject position (sometimes called a pleonastic or expletive), it is labeled as expl or better expl:impers

Si può procedere .
expl:impers(procedere, Si)

NB Note that when the verb is used in the passive voice the nominal syntactic subject is marked with the subtype nsubj:pass. When the subject is clausal, it’s preferable to use other specialized relations (csubj or its subtype csubj:pass).
