Poorer girl turned up in elevated check (7)
I believe the answer is:
needier
'poorer' is the definition.
('needy' can be similar in meaning to 'poor')
'girl turned up in elevated check' is the wordplay.
I cannot really understand how this works, but
'girl' could be 'edie' and 'edie' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for needier that I've seen before include "Less well off" , "Poorer" , "Those with fewer resources are" , "more impoverished" , "In more want" .)
