Current very hot? Not right (7)
I believe the answer is:
topical
'current' is the definition.
('topical' can be similar in meaning to 'current')
'very hot? not right' is the wordplay.
'very hot?' becomes 'tropical' (I've seen this before).
'not' indicates named letters should be taken away.
'right' becomes 'r' (common abbreviation).
'tropical' with 'r' taken out is 'TOPICAL'.
(Other definitions for topical that I've seen before include "Related to current affairs" , "Up to date" , "Having reference to current events" , "Applied externally" , "Dealing with current affairs" .)
