This question already has an answer here:
I've seen a few questions dotted around, which require references to dictionaries or such-like (etymonline, wiktionary, OE dictionary, the Chicago Manual of Style), to make clear why a word or correction you're submitted as an answer is correct.
Is there any preference on which of these to go for? I've seen definitions citing wiktionary be both sufficient and severely lacking. As well as this I worry that people constantly referencing the Chicago Manual of Style it might give incorrect answers to people looking for British English style help.
Obviously a well phrased question, stating how much detail and accuracy is required, as well as a well researched answer should circumvent this issue. Is there any official guideline on this matter? I have seen this post, which is quite helpful, but it seems that it outlines a preference. Wiktionary is the 4th (?) answer given, and whilst I prefer it, I don't count it as a legitimate source in the same way most academics cringe at the idea of referencing wikipedia in their papers.
Perhaps a well written, "How to reference your answers" would make a good addition to the FAQ? That is if I haven't missed this sort of guideline that is there already.
