Sweets in lounge I put by old man (9)
I believe the answer is:
lollipops
'sweets' is the definition.
(lollipop is a kind of sweet)
'lounge i put by old man' is the wordplay.
'lounge' becomes 'loll' (both can mean to sit in a relaxed way).
'put by' is a charade indicator (letters next to each other).
'old man' becomes 'pops' (I've seen this in another clue).
'loll'+'i'+'pops'='LOLLIPOPS'
'in' is the link.
(Other definitions for lollipops that I've seen before include "Gobstoppers" , "Sweets on sticks" , "Sweets - popular works of classical music" .)
