Suffers, made to conclude certain change is needed (7)
I believe the answer is:
endures
'suffers' is the definition.
('endure' can be a synonym of 'suffer')
'to conclude certain change is needed' is the wordplay.
'to conclude' becomes 'end' (I've seen this before).
'certain change' becomes 'ures' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'is needed' says to put letters next to each other.
'end'+'ures'='ENDURES'
'made' acts as a link.
Can you help me to learn more?
(Other definitions for endures that I've seen before include "Tolerates" , "Lasts or puts up with" , "Suffers or lasts" , "Bears" , "Ensured (anag.)" .)
