Witty talk not good during a particular period (8)
I believe the answer is:
badinage
'witty talk' is the definition.
'badinage' can be an answer for 'talk' (I have seen 'Frivolous talk' mean 'badinage' so perhaps 'talk' could also mean 'badinage'). I'm unsure of the 'witty' bit.
'not good during a particular period' is the wordplay.
'not good' becomes 'bad' (bad is the opposite of good).
'during' becomes 'in' (e.g. during February means in February).
'a particular period' becomes 'age' (age is a kind of period. I am not sure about the 'particular' bit.).
'bad'+'in'+'age'='BADINAGE'
Can you help me to learn more?
(Other definitions for badinage that I've seen before include "Amiable banter" , "Josh" , "Raillery, give-and-take" , "bit of playful repartee" , "Ribbing" .)
