Is anyone an exocentric compound word?

Answer 1

I am not an expert on this but, yes, I think it can be. Here's why:

Anyone is a pronoun.

Any is an adjective, determiner, pronoun or adverb.

One is a determiner, a number, a person, a thing, a noun, an adjective or it can be used as a pronoun.

A further example: The noun bittersweet is an exocentric compound, since it is a noun but its elements are both adjectives. (But, yes, bittersweet can also be used as an adjective!) [Example borrowed from dictionary.com]

Answer 2

Yes, the word "thunderbird" is an exocentric compound word because it does not have a head with a clear dominant meaning.
