Speech at end of month to present gong? (10)
I believe the answer is:
decoration
'gong?' is the definition.
'speech at end of month' is the wordplay.
'speech' becomes 'oration' (oration is a kind of speech).
'at end of' says to put letters next to each other.
'month' becomes 'dec' (Dec is an example).
'oration' after 'dec' is 'DECORATION'.
'to present' is the link.
(Other definitions for decoration that I've seen before include "Flags put out" , "Ornaments - medal" , "Medal; ornament" , "award" , "New Year's honour, say" .)
