Line on chauffeur’s pants (6)
I believe the answer is:
drivel
'line on chauffeur's pants' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'line on chauffeur's' is the wordplay.
'line' becomes 'l' (used when specifying particular lines from a poem).
'on' is a charade indicator (letters next to each other).
'chauffeur' becomes 'drive' (chauffer can mean to drive around).
'l' after 'drive' is 'DRIVEL'.
Can you help me to learn more?
(Other definitions for drivel that I've seen before include "Stuff and nonsense" , "Worthless, foolish nonsense" , "Verbal nonsense, rubbish" , "Balls" , "Foolishness" .)
