She provides maternal care for a small charge (6,6)
I believe the answer is:
foster mother
'charge' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'she provides maternal care for a small' is the wordplay.
I cannot quite understand how this works, but
'she' could be 'her' (I've seen this in other clues) and 'her' is present in the answer.
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for foster mother that I've seen is " carer".)
