Traveller is said to be a lot better looking (8)
I believe the answer is:
wayfarer
'traveller' is the definition.
(I know that wayfarer is a type of pedestrian)
'said to be a lot better looking' is the wordplay.
I cannot really understand how this works, but
'be' could be 'are' (I've seen this in another clue) and 'are' is found in the answer.
'a' is found in the answer.
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 wayfarer that I've seen before include "One walking" , "Bird of passage" , "Traveller, especially on foot" , "Foot-traveller" , "Person on a journey - sailing dinghy" .)
