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.
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
NB
Note that when the verb is used in the passive voice the nominal syntactic subject is marked as nsubjpass
.
When the subject is clausal, it’s preferable to use other specialized relations (csubj or csubjpass).
