Speak without second impudence (3)
I believe the answer is:
lip
'impudence' is the definition.
(lip is a kind of impudence)
'speak without second' is the wordplay.
I cannot quite see how this works, but
'without second' could be 'i' (2nd letter of 'without') and 'i' is found within the answer.
The remaining letters 'lp' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lip that I've seen before include "giving such insincere service" , "Edge; impudent talk" , "Impudent talk from part of the face" , "Aural impudence" , "In slang, impudent talk" .)
