Weak and delicate, making fellow complain (5)
I believe the answer is:
frail
'weak and delicate' is the definition.
(I've seen this in another clue)
'fellow complain' is the wordplay.
'fellow' becomes 'F' (abbreviation - of a society etc.).
'complain' becomes 'rail' (railing is a kind of complaining).
'f'+'rail'='FRAIL'
'making' acts as a link.
(Other definitions for frail that I've seen before include "old and weak" , "Decrepit" , "isn't sturdy" , "Physically feeble" , "Puny" .)
