Humour or common sense (3)

I believe the answer is:

wit

(Other definitions for wit that I've seen before include "Ingenuity; wag" , "Funny person" , "Humour or common sense" , "Cleverness with words and ideas" , "'Brevity is the soul of ...'" .)

I've seen this clue in the Irish Times (Simplex) and The Irish Times.
