Is the word a word?

That's a tricky question! It depends on how you interpret it:

* Literally: The word "a" is a word. It's a definite article, used to specify a single, particular thing.

* Recursively: The sentence "Is the word 'a' a word?" contains the word "a" within it. So, in a way, it's asking if the word "a" appears in the question itself, and the answer is yes!
