Require your start to be poor (5)
I believe the answer is:
needy
'poor' is the definition.
('needy' can be similar in meaning to 'poor')
'require your start to' is the wordplay.
'require' becomes 'need' ('need' can be a synonym of 'require').
'start to' indicates taking the first letters.
The initial letter of 'your' is 'y'.
'need'+'y'='NEEDY'
'be' acts as a link.
(Other definitions for needy that I've seen before include "Necessitous" , "Poor; indigent" , "Impecunious" , "Poor; wanting affection" , "badly craving affection" .)
