Charming party held by great guy you hardly know (12)
I believe the answer is:
acquaintance
'know' is the definition.
(thesaurus)
'charming party held by great guy you hardly' is the wordplay.
I cannot quite see how this works, but
'charming' could be 'quaint' (I've seen this before) and 'quaint' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for acquaintance that I've seen before include "contact" , "Person known slightly" , "Slight knowledge" , "Someone one knows slightly" , "Person one knows slightly" .)
