Stop to get air (7)
I believe the answer is:
refrain
This clue is a double definition.
'stop' is the first definition.
(I've seen this before)
'air' is the second definition.
(thesaurus)
'to get' acts as a link.
(Other definitions for refrain that I've seen before include "Stop - chorus" , "Chorus; desist" , "Chorus; keep away (from)" , "Lines repeated at the end of each verse" , "recurring phrase" .)
