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).
