She, Iga, can be an entertainer in Japan (6)
I believe the answer is:
geisha
'an entertainer in japan' is the definition.
I can't judge whether this definition defines the answer.
'she iga can be' is the wordplay.
'can be' indicates anagramming the letters.
'she'+'iga'='sheiga'
'sheiga' anagrammed gives 'GEISHA'.
Can you help me to learn more?
(Other definitions for geisha that I've seen before include "Professional female companion for Japanese men" , "One employed to look after men" , "Japanese woman trained to please men" , "Japanese hostess trained to entertain men" , "Japanese hostess who entertains men" .)
