Chap from Lechlade (3)
I believe the answer is:
lad
'chap' is the definition.
(I know that chap can be written as lad)
'from lechlade' is the wordplay.
'from' indicates the answer is hidden within the clue.
'LAD' is hidden within 'lechlade'.
(Other definitions for lad that I've seen before include "Youngster" , "Young fellow" , "Son" , "Scottish lover" , "(Housman's Shropshire) boy" .)
