Polish bottom of tray, love (5)
I believe the answer is:
honey
'love' is the definition.
(synonyms)
'polish bottom of tray' is the wordplay.
'polish' becomes 'hone' (I've seen this in another clue).
'bottom of' indicates one should take the final letters.
The final letter of 'tray' is 'y'.
'hone'+'y'='HONEY'
(Other definitions for honey that I've seen before include "Sweet yellow liquid" , "Product of bees; darling" , "Hive fluid" , "Sweet product of insects" , "Food from hive" .)
