Represent someone myself -- that's provided for everything (9)
I believe the answer is:
personify
'represent' is the definition.
(personifying is a kind of representing)
'someone myself that's provided for everything' is the wordplay.
I cannot really see how this works, but
'someone' could be 'person' ('person' can be a synonym of 'someone') and 'person' is present in the answer.
'myself' could be 'i' and 'i' is present in the answer.
The remaining letters 'fy' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for personify that I've seen before include "Be the embodiment of" , "Embody in human form" , "Represent; embody" .)
