Characters in Co Antrim can be amorous (8)
I believe the answer is:
romantic
'be amorous' is the definition.
(I've seen this before)
'characters in co antrim' is the wordplay.
'characters in' indicates anagramming the letters.
'co'+'antrim'='coantrim'
'coantrim' anagrammed gives 'ROMANTIC'.
'can' acts as a link.
(Other definitions for romantic that I've seen before include "Amatory" , "Having an idealised view of reality" , "Soulful or amourous idealist" , "Amorous, showing loving feeling" , "Soulful or amorous idealist" .)
