Chap from Elgin (5)
I believe the answer is:
nigel
'chap' is the definition.
'from elgin' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'elgin' with letters rearranged gives 'NIGEL'.
(Other definitions for nigel that I've seen before include "Man's name" , "-- Kennedy, violinist" , "Fellows sometimes called this" , "One knighted by Conan Doyle," , "--- Pargetter, (Archers)" .)
