Theatrical performance allowed daughter to participate in display of poise (6-7)
I believe the answer is:
ballet-dancing
'theatrical' is the definition.
Both the answer and definition are adjectives.
Maybe there's an association between them I don't understand?
'performance allowed daughter to participate in display of poise' is the wordplay.
I cannot really see how this works, but
'allowed' could be 'let' (to let is to allow or permit) and 'let' is located in the answer.
'daughter' could be 'd' (genealogical abbreviation) and 'd' is located in the answer.
'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for ballet-dancing that I've seen is " Terpsichorean art".)
