Pass for one is in Bayeux (5)
I believe the answer is:
egest
'pass' is the definition.
(synonyms)
'for one is in bayeux' is the wordplay.
I cannot quite see how this works, but
'for one' could be 'eg' (both can mean 'for example') and 'eg' is located in the answer.
The remaining letters 'est' 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).
Can you help me to learn more?
(Other definitions for egest that I've seen before include "empty" , "void" .)
