Abode accommodating British guy (6)
I believe the answer is:
hombre
'guy' is the definition.
('hombre' can be a synonym of 'guy')
'abode accommodating british' is the wordplay.
'abode' becomes 'home' (home is a kind of abode).
'accommodating' means one lot of letters goes inside another.
'british' becomes 'br'.
'home' going around 'br' is 'HOMBRE'.
(Other definitions for hombre that I've seen before include "American man" , "Spanish fellow" , "Western guy" , "A man (Sp)" .)
