Declared, maintained (7)
I believe the answer is:
alleged
I believe this is a double definition.
'declared' is the first definition.
(similar in meaning)
'maintained' is the second definition.
(alleging is a kind of maintaining)
(Other definitions for alleged that I've seen before include "Doubtful; claimed" , "Purported" , "Declared without being able to prove" , "So-called" , "Stated without proof" .)
