Time reversed with tin drum (5)
I believe the answer is:
snare
'drum' is the definition.
(I know that snare is a type of drum)
'time reversed with tin' is the wordplay.
'time' becomes 'era' (era is a kind of time).
'reversed' says the letters should be written in reverse.
'with' says to put letters next to each other.
'tin' becomes 'Sn' (Sn is the chemical symbol for tin).
'era' reversed gives 'are'.
'are' after 'sn' is 'SNARE'.
(Other definitions for snare that I've seen before include "Catch" , "Entrap" , "Kind of trap, often with noose" , "Lure or trap" , "Noosed trap" .)
