Anger about chartered accountant’s girl (5)
I believe the answer is:
erica
'girl' is the definition.
(I've seen this before)
'anger about chartered accountant's' is the wordplay.
'anger' becomes 'ire' ('ire' can be a synonym of 'anger').
'about' says the letters should be written backwards.
'chartered accountant' becomes 'ca'.
'ire' backwards is 'eri'.
'eri'+'ca'='ERICA'
(Other definitions for erica that I've seen before include "Woman" , "Female" , "found on the moors" , "Moorland plant, girl's name" , "growing up on the moors" .)
