用法筆記

The phrases 'on topic' (relevant) and 'off topic' (not relevant) are common adjectival uses of the word. 'On topic' is used after 'be' or 'stay' and cannot go before a noun ('an on-topic answer' is rare). 'Off topic' works both after 'be' and as a hyphenated adjective before a noun ('off-topic comments').
