Such questions are not off-topic, per se. You have generalised from the particular.
If there's a "write-in" reason for casting a close vote, then it doesn't get mentioned in the close banner, but it can be inferred from the question timeline and the list of comments under the question.
Four close votes (the original plus the three comment up-votes) used this reason:
I’m can voting [sic] to close this question. A dictionary offers different synonyms of a word, because each applies differently. If one fits where others don't, what is the problem?
The other effective close vote used the standard "not enough research" reason.
Your question needs to show your research.
However: the comments on the version on Philosophy.SE are also telling.
This belongs on ELU, not here. The accepted ELU answer is correct, except for the last line: 'account' is commonly use in intellectual circles for descriptions that don't rise to the level of a formal theory or model. But no one's perfect. There's no sense starting a cross-site debate, so I'm voting to close this. – Ted Wrigley Jan 13 at 16:09
I agree with Ted. "Account" is something more than "approach" but that does not rise to the level of a "theory", "model" is rarely used this way in philosophy. But the use is vague and not regimented, it is more of a colloquial choice. – Conifold Jan 13 at 21:26
You have already accepted an answer, which was given even though the question needs to show more research.
