Cutting bit of wordplay by posh bloke (7)
I believe the answer is:
pungent
'cutting' is the definition.
(thesaurus)
'bit of wordplay by posh bloke' is the wordplay.
'bit of wordplay' becomes 'pun' (punning is a type of wordplay).
'by' says to put letters next to each other.
'posh bloke' becomes 'gent' (both can mean a man. I am not sure about the 'posh' bit.).
'pun'+'gent'='PUNGENT'
Can you help me to learn more?
(Other definitions for pungent that I've seen before include "Sharp tasting/smelling" , "delivering powerful smack" , "Strong and sharp" , "spicy" , "Acrid - painful" .)
