Praise song and dance on allotment (9)
I believe the answer is:
adoration
'praise' is the definition.
(I've seen this before)
'song and dance on allotment' is the wordplay.
'song and dance' becomes 'ado' (ado can mean a commotion or fuss).
'on' is a charade indicator (letters next to each other).
'allotment' becomes 'ration' (I've seen this in another clue).
'ado'+'ration'='ADORATION'
(Other definitions for adoration that I've seen before include "Hero-worship" , "Deep love and respect" , "Feeling of profound love" , "holding someone up a lot" , "Honour" .)
