More pleasant resort — first in Riviera (5)
I believe the answer is:
nicer
'more pleasant' is the definition.
('nice' is associated in meaning with 'pleasant')
'resort aeur first in riviera' is the wordplay.
I cannot really see how this works, but
'resort' could be 'nice' (French coastal resort) and 'nice' is located in the answer.
'first in riviera' could be 'r' (1st letter of 'riviera') and 'r' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nicer that I've seen before include "improved" , "Kinder; finer" , "Pleasanter" , "More pleasant or fine" , "More pleasant or courteous" .)
