As a more general version of this question, do we want the relationships between Latin and other languages (both preceding and following) to be on-topic?
I'd answer yes to both.
I'd definitely answer yes to the relationship to languages preceding. The relationship between Latin and any other preceding language is, almost by definition, significantly related to Latin.
The relationship between Latin and following languages is a little fuzzier. We wouldn't want questions that are really about English words which happen to have Latin roots. I would be comfortable allowing questions about the etymology of words, at least to start.
If it becomes a problem, we can shut them down.
