This came up recently on this question about the the etymology of イギリス. We've already got a question about イギリス vs. イングランド, where the answer happens to contain the etymology as well.
In this case, the matter gets even more complicated. The main question is about イギリス vs. イングランド, but it also says: And as a side question, where does the word イギリス come from?
Answers often need to elaborate on a certain aspect and may contain more details than might have been asked for. In general, should we mark a question as a duplicate of another and different question if one of its answers includes the answer?
Should such a question be marked as a duplicate? Should we edit the old question or title? Should we do something else; or nothing at all?
A few more examples:
- Question about the difference きらい vs. すきじゃない; answers include 苦手,憎む,大好き,大嫌い.
- Question about the difference 森 vs 林; answer includes vs. 森林
- Question about the meaning of も and また; the answer includes an answer to the meanings of 上(above/right/preceeding) 下(below/left/following)
- Question about ほしがる vs. ほっする; answer contains the usage of 浴【よく】する
- Question about the meaning of 可哀想 in a certain context; answer includes a paragraph on dropping the last letter ありがとう→ありがと
As a side question, I was wondering if we should we remove side questions
from questions?
