Definition
Verbal adjuncts have functions like those of English prepositions and as a result may also be called “prepositional verbs”. These secondary verbs specify location, direction of motion, and a few notions of other sorts expressed by English prepositions. Most, if not all, can appear as predicate heads. (Suttles, 2003, p. 70)
