Brother — one who works in chippy, do we hear? (5)
I believe the answer is:
friar
'brother' is the definition.
(thesaurus)
'one who works in chippy do we hear?' is the wordplay.
'one who works in chippy' becomes 'fryer'.
'do we hear?' shows a homophone (sound like).
'fryer' sounds like 'FRIAR'.
(Other definitions for friar that I've seen before include "Eg, a Franciscan" , "..... Tuck was one of Robin Hood's men" , "Religious brother" , "Mendicant priest" , "Mendicant preacher" .)
