Spoke crisply in the Paris patois (4)
I believe the answer is:
spat
'spoke crisply' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe you can see an association between them that I can't see?
'in the paris patois' is the wordplay.
'in' indicates a hidden word.
'SPAT' can be found hidden inside 'paris patois'.
Can you help me to learn more?
(Other definitions for spat that I've seen before include "angry words" , "Reacted contemptuously" , "Minor argument" , "Small quarrel between Pats" , "Little quarrel - leg wear" .)
