Handle holding hot hazard (6)
I believe the answer is:
threat
'hazard' is the definition.
(I've seen this in another clue)
'handle holding hot' is the wordplay.
'handle' becomes 'treat' (synonyms).
'holding' means one lot of letters goes inside another.
'hot' becomes 'h' (abbreviation eg on taps).
'treat' placed around 'h' is 'THREAT'.
(Other definitions for threat that I've seen before include "An intimidatory warning" , "Hazard" , "Intimidatory words to exact compliance" , "Warning of intent to harm" , "Menacing words" .)
