The expletive is an introductory word followed by the adjective.
true or false

False.

Explanation:

Expletive is a word derived from the Latin word "expletivus" meaning "to fill out" that is infused in a sentence either to emphasize the meaning or to confer to the meter. These do not add to the basic meaning of the sentence but not completely insignificant or futile as it enhances the tone of the statement. It is an introductory word often employed in the sentence to fill the gaps usually followed by verbs. For example;

1. There is no place like home.

2. Here is the professor of my class.

Here, both sentences introduced with expletive i.e. (There, Here) but followed by verb, not by adjectives. Thus, the assertion is false.
