She gives her dad the pip (5)
I believe the answer is:
pippa
'she' is the definition.
'her dad the pip' is the wordplay.
I cannot really understand how this works, but
'dad' could be 'pa' (both can mean one's father) and 'pa' is present in the answer.
'the pip' could be 'pip' and 'pip' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'gives' acts as a link.
Can you help me to learn more?
(Other definitions for pippa that I've seen before include "-- Passes (Browning)" , "she passes in verse composition" , "woman" .)
