We recently had a question where a usage example was given, along with an attempt at part-of-speech tagging, and a request to validate that tagging:
A user then closed the question in a non-voting process because "we [do not] fully break down the grammatical structure of random words".
So, is this sort of question valid here? I strongly feel it should be - exploring part-of-speech tagging is an important exercise when learning language, and a lot of information can be precisely communicated efficiently about sentence structure when this skill is practiced and used.
Additionally, I don't see anything written in the definition of "on-topic" at https://ell.stackexchange.com/help/on-topic that endorses this closure.
On the contrary, questions about "grammar" are listed as on-topic, and none of the "off-topic" bullet-point examples seem to apply to this question.
Should it be reopened? Should questions like this one be closed in the future, or answered?
