Kitty I make the mistake of introducing to the entertainer (7)
I believe the answer is:
pierrot
'the entertainer' is the definition.
(stock theatrical character)
'kitty i make the mistake of introducing' is the wordplay.
I cannot quite understand how this works, but
'i' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'mistake' could be 'err' (synonyms) and 'err' is found in the answer.
'of' could be 'o' and 'o' is found within the answer.
A single letter 'p' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for pierrot that I've seen before include "Male clown from French pantomime" , "Period; incantation" , "In French panto, clown with white face and baggy costume" , "Sad white-faced clown" , "Seaside clown" .)
