As one at first approaches, fancy going over the top? (6)
I believe the answer is:
agreed
'as one' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'first approaches fancy going over the top?' is the wordplay.
I cannot quite understand how this works, but
'first' could be 'a' (first letter of the alphabet) and 'a' is located in the answer.
'over' could be 're' and 're' is located in the answer.
The remaining letters 'ged' 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).
'at' is the link.
Can you help me to learn more?
(Other definitions for agreed that I've seen before include "I'll go along with that" , "Mutually settled" , "Okayed" , "Consented, settled" , "Tallied - reconciled" .)
