The agreement is forwarded (6)
I believe the answer is:
assent
'the agreement' is the definition.
(assent is a kind of agreement)
'forwarded' is the wordplay.
I cannot quite see how this works, but
'forwarded' could be 'sent' (I've seen this in other clues) and 'sent' is located in the answer.
The remaining letters 'as' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'is' acts as a link.
Can you help me to learn more?
(Other definitions for assent that I've seen before include "Give consent" , "Say yes" , "Consent or approval" , "Acquiesce, comply" , "Expression of agreement" .)
