Sad English member upset CIA (7)
I believe the answer is:
elegiac
'sad' is the definition.
(I've seen this before)
'english member upset cia' is the wordplay.
'english' becomes 'e' (abbreviation).
'member' becomes 'leg' (member can mean a limb).
'upset' is an anagram indicator.
'cia' with letters rearranged gives 'iac'.
'e'+'leg'+'iac'='ELEGIAC'
(Other definitions for elegiac that I've seen before include "Thoughtful" , "Plaintive" , "Mournful or sad as poem may be" , "Poetic, mournful" , "Lie in cage being poetically mournful" .)
