Reminder about being associated with people posh and arrogant (5)
I believe the answer is:
proud
'arrogant' is the definition.
(similar in meaning)
'reminder about being associated with people posh' is the wordplay.
I cannot really see how this works, but
'being' could be 'pro' (pro is a kind of being) and 'pro' is found in the answer.
'posh' could be 'u' (abbreviation for upper-class - opposite to non-U) and 'u' is found in the answer.
A single letter 'd' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for proud that I've seen before include "Conscious of one's own dignity" , "With high self-opinion" , "Feeling gratified or arrogant" , "Guilty of deadly sin" , "Slightly projecting; imposing" .)
