needy

I'm a little stuck... Click here to teach me more about this clue!

'very poor' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for needy that I've seen before include "wanting much" , "Wanting attention" , "Insecure; very poor" , "Disadvantaged" , "Impecunious" .)

I've seen this clue in The Times and The Sunday Times.
