Group of characters from Bath, pale in resort (8)
I believe the answer is:
alphabet
'group of characters' is the definition.
(I've seen this before)
'bath pale in resort' is the wordplay.
'in resort' indicates anagramming the letters.
'bath'+'pale'='bathpale'
'bathpale' anagrammed gives 'ALPHABET'.
'from' is the link.
(Other definitions for alphabet that I've seen before include "Whole set of letters" , "Letters, symbols used in a writing system" , "Set of letters used in writing" , "series of letters" , "A language's set of letters" .)
