1. superfluous addition; something unnecessary
An unnecessary addition that spoils or detracts from what was already complete. From a Chinese fable in which a man, having drawn a snake faster than anyone else, ruined his picture by adding legs to it. Literally 'snake legs.'
蛇足(だそく)かもしれない、ひとつ()(くわ)えたい
This may be unnecessary, but I'd like to add one thing.
I added an explanation, but it may have been superfluous.
At the risk of belaboring the point, let me mention just one more precaution.

Usage

蛇足(だそく) is often used as a polite hedge before adding a comment the speaker suspects may be unnecessary. The phrase 蛇足(だそく)ながら or 蛇足(だそく)かもしれない serves as a softener. It is common in writing and formal speech.

Etymology

From a Chinese fable (故事(こじ)成語(せいご)) in which contestants raced to draw a snake. The winner finished first but then added legs, disqualifying his entry. The moral: do not ruin a good thing by adding what is not needed.
