nsubj: nominal subject

A nominal subject (nsubj) is a nominal which is the syntactic subject and the proto-agent of a clause. That is, it is in the position that passes typical grammatical test for subjecthood, and this argument is the more agentive, the do-er, or the proto-agent of the clause. (See csubj for when the subject is clausal. See nsubjpass and csubjpass for when the subject is not the proto-agent argument due to valence changing operations.) This nominal may be headed by a noun, or it may be a pronoun or relative pronoun, or in ellipsis contexts, other things such as an adjective.

«!- 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. If there is then a displaced subject in the clause, as in the English existential there construction, it will be labeled as nsubj.) –>

The governor of the nsubj relation might not always be a verb: when the verb is a copular verb, the root of the clause is the complement of the copular verb, which can be an adjective or noun, including a noun marked by a preposition, as in the examples below.

nsubj(outro, tom)

Note that when the subject appears after the verb, it is still tagged as nsubj.

nsubj(povo-3, povo-7)

Note that complex subjects are treated as conjunctions and only the first element of the conjunction holds the nsubj relation.
