Exocentric compound words are those where the meaning of the whole word is not simply the sum of the meanings of its parts. Instead, the meaning is determined by the context or a metaphorical relationship. Examples of exocentric compounds include:
* pickpocket (not a pocket that picks, but a person who steals from pockets)
* high-handed (not a hand that is high, but a manner of behaving arrogantly)
* scarecrow (not a crow that scares, but a figure used to scare crows)
"Anyone" is a simple word with its own meaning. It doesn't have parts that can be analyzed separately to understand its meaning. It's simply a pronoun that refers to any person.
Therefore, "anyone" is not an exocentric compound word.
