Sense sign of hesitation about article (3)
I believe the answer is:
ear
'sense' is the definition.
(I know that ear is a type of audition)
'sign of hesitation about article' is the wordplay.
'sign of hesitation' becomes 'er'.
'about' is an insertion indicator.
'article' becomes 'a' (the indefinite article in English).
'er' enclosing 'a' is 'EAR'.
(Other definitions for ear that I've seen before include "good sense of music" , "organ with drum" , "Auricle" , "Bit of corn" , "Hammer in this" .)
