One with hot possessions trying to avoid the heat? (7)
I believe the answer is:
burglar
'one' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for burglar that I've seen before include "House thief" , "Thief who enters a building to steal" , "One enters a building in order to steal" , "House-violating thief" , "One breaking in" .)
