While it sounds like a word that might describe someone who studies words or language, there are more specific and established terms for that:
* Linguist: A person who studies the structure, development, and use of language.
* Lexicographer: Someone who compiles dictionaries.
* Etymologist: A person who studies the origin and history of words.
* Semanticist: A person who studies the meaning of words.
It's possible that "wordologist" could be a made-up word or a term used in a specific niche or context. If you encountered it somewhere, please provide more information about where you saw it, and I can help you understand its meaning.
