She provides a home for a man's heart (5)
I believe the answer is:
nesta
'she' is the definition.
'a home for a man's heart' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
'home' could be 'nest' (a bird's home) and 'nest' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'provides' acts as a link.
Can you help me to learn more?
(Other definitions for nesta that I've seen before include "woman" , "girl" .)
