Stop in a few bars? (7)
I believe the answer is:
refrain
'stop' is the definition.
(I've seen this before)
'in a few bars' is the wordplay.
I cannot really understand how this works, but
'in' is within the answer.
'a' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for refrain that I've seen before include "Chorus; desist" , "Hold back" , "tune" , "Words repeated after verses" , "Repeating line in a song, poem" .)
