That tax-exempt girl, remember (5)
I believe the answer is:
tessa
'that tax-exempt' is the definition.
I can't judge whether this defines the answer.
'girl remember' is the wordplay.
I cannot quite see how this works, but
'girl' could be 'tess' and 'tess' is present in the answer.
A single letter 'a' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tessa that I've seen before include "Dahl or Jowell" , "Girl's name; former savings account" , "Girl" , "Girl's name, forerunner of ISA" , "Tax-exempt special savings account" .)
