Partly clipped, it may be curled (3)
I believe the answer is:
lip
'it may be curled' is the definition.
The definition suggests a singular noun which matches the answer.
'partly clipped' is the wordplay.
'partly' indicates the answer is hidden within the clue (part of the clue is used).
'LIP' can be found hidden inside 'clipped'.
Can you help me to learn more?
(Other definitions for lip that I've seen before include "Oral impudence?" , "Top edge of a vessel" , "Sauce" , "sauciness" , "Insolence (slang)" .)
