Dear English experts,
I need your expertise to see which of the following sentences is correct :-
They sort of complement each other OR
They are a sort of complementing each other
OR
They are a sort of complementing to each other
The usage changes with the indefinite article "a". An article is only used before a noun. Thus, "a sort of" is different from "sort of", the latter being an adverb, meaning somewhat, not completely.
This is from the AHD:
kind of
Also,
sort of. Rather, somewhat, as in I'm kind of hungry, or The bird looked sort of like a sparrow. [Colloquial; c. 1800] This usage should not be confused with a kind of or a sort of, which are much older and refer to a borderline member of a given category (as in a kind of a shelter or a sort of a bluish color). Shakespeare had this usage in Two Gentlemen of Verona (3:1): “My master is a kind of a knave.” Also see of a kind.
