Topic 3.6: Heads and Complements
As mentioned before, a constituent needs a head. The head of a phrase has restrictions as to what it
allows in a phrase.
For example, a VP contains a V as a head, and it may require other constituents as well. Consider this
the child put the puppy in the garden.
In this sentence the verb put needs something to complete it. We cannot say the child put.
Verbs that need an object to complete the meaning are called transitive verbs. Verbs that behave that
way include find, take, grab, etc.
