smart

I'm a little stuck... Click here to teach me more about this clue!

'do sting' is the definition.
'smart' can be an answer for 'sting' (I've seen this before). I am unsure of the 'do' bit.

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for smart that I've seen before include "Chic - hurt" , "Fashionable" , "Well-dressed" , "well-kept" , "Clean, tidy; clever" .)

I've seen this clue in The Times.
