A word we hear in a German accent? So it's alleged (7)
I believe the answer is:
averred
'alleged' is the definition.
('aver' can be a synonym of 'allege')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for averred that I've seen before include "Claimed" , "Stated, asserted" , "confidently stated" , "Asserted to be the case" , "Stated to be the case" .)
