She gives mother fresh heart (3)
I believe the answer is:
mae
'she' is the definition.
(I've seen this before)
'mother fresh heart' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'heart' indicates the central letters.
The central letter of 'fresh' is 'e'.
'ma'+'e'='MAE'
'gives' acts as a link.
(Other definitions for mae that I've seen before include "Woman" , "Girl" , "-- West, C-twenty actress" , "The first Hollywood blonde femme fatale, . . . West" , "- - West, movie vamp" .)
