Entertainer who made some error in a mine? (7)
I believe the answer is:
pierrot
'entertainer' is the definition.
(stock theatrical character)
'made some error in a mine?' is the wordplay.
'made' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'some' indicates the central letters.
'in' indicates putting letters inside.
'a mine?' becomes 'pit' (down the pit).
The centre of 'error' is 'rro'.
'e'+'rro'='erro'
'erro' going into 'pit' is 'PIERROT'.
'who' is the link.
Can you help me to learn more?
(Other definitions for pierrot that I've seen before include "Aged entertainer" , "French pantomime character with a white face" , "I report on French pantomime clown" , "Period; incantation" , "Type of clown" .)
