How one might deny being frigid? (5)
I believe the answer is:
hotly
'how' is the definition.
Both the answer and definition are adverbs. Perhaps you can see a link between them that I can't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hotly that I've seen before include "showing passion" , "showing eagerness" , "disputed thus?" , "With zeal - as one may be pursued" , "in an ardent manner" .)
