Put back soprano and tenor in music on a single (8)
I believe the answer is:
postpone
'music on a single' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how they can define each other.
'put back soprano and tenor in' is the wordplay.
'put' becomes 'pose' (posing is a kind of putting).
'back soprano' becomes 'pon' (I can't justify this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'tenor' becomes 't'.
'in' indicates putting letters inside.
'pon' put after 't' is 'tpon'.
'pose' enclosing 'tpon' is 'POSTPONE'.
Can you help me to learn more?
(Other definitions for postpone that I've seen before include "Put off till later" , "'Hold over, defer (8)'" , "Put off until future date" , "pigeon-hole" , "Put off till another time" .)
