Subcategorization frame

MORPHOLOGY/SYNTAX: a formalization of the notion of subcategorization. EXAMPLE: (i) gives the strict subcategorization frame of the verb hit. It says that the pseudo-transitive verb hit optionally (indicated by the parentheses) selects an NP-complement (a sister-node, as indicated by the square brackets) to its right (indicated by the order '__ NP' rather than 'NP __').

(i) hit: [ __ (NP)]
