root: root

The root of a sentence is the predicate of the main clause. This may be a verb (1), a predicate adjective (2), or a nominal in a copular construction (3). Sometimes only an auxiliary (see AUX) is present, in which case that will be promoted to root (4). If there is only a phrase, whatever is the governor of that phrase will be the root (5).
