Endorse fraternity boldly neglecting rent (6)
I believe the answer is:
ratify
'endorse' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ratify that I've seen before include "OK" , "Approve and sign" , "Affirm" , "Approve officially" , "Give validity to" .)
