Relaxed, having large charity to support (4-4)
I believe the answer is:
laid-back
'relaxed' is the definition.
(I've seen this before)
'large charity to support' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'charity' becomes 'aid' (eg foreign aid).
'to support' becomes 'back' (to back is to support or endorse).
'l'+'aid'+'back'='LAID-BACK'
'having' acts as a link.
(Other definitions for laid-back that I've seen before include "Easygoing and relaxed like cabal kid" , "Ultra-cool!" , "Relaxed (colloq.)" , "Unhurried and relaxed" .)
