more cordial (5)
I believe the answer is:
nicer
'more cordial' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nicer that I've seen before include "it's more appealing" , "relatively pleasant" , "Pleasanter" , "Kinder; finer" , "More pleasant, French resort close to Montpellier" .)
