Candlemas to Lent, not entirely hot (6)
I believe the answer is:
stolen
'hot' is the definition.
(I've seen this before)
'candlemas to lent not entirely' is the wordplay.
'not entirely' says the answer is hidden in the clue.
'STOLEN' is hidden within 'candlemas to lent'.
(Other definitions for stolen that I've seen before include "Hot item" , "Pilfered" , "Taken unlawfully" , "Taken without the owner's consent" , "subject to plagiarism" .)
