anita

I'm a little stuck... Click here to teach me more about this clue!

'a consumer overheard' is the definition.
I can't judge whether this defines the answer.

'a girl' is the wordplay.
'girl' becomes 'nita' ().
'a'+'nita'='ANITA'

Can you help me to learn more?

(Other definitions for anita that I've seen before include "-- Brookner, English novelist" , "- Loos (Gentlemen Prefer Blondes)" , "Woman" , "girl produced" , "eg Dobson or Roddick" .)
