Ring found back in allotment (4)
I believe the answer is:
toll
'ring' is the definition.
(tolling is a kind of ringing)
'found back in allotment' is the wordplay.
'back' is a reversal indicator.
'found' says the answer is hidden in the clue.
'llot' can be found hidden inside 'in allotment'.
'llot' backwards is 'TOLL'.
(Other definitions for toll that I've seen before include "Ring bell slowly as for funeral" , "Ring - duty" , "Spout" , "Payment imposed for the use of a public road" , "Peal, chime" .)
