Accommodating chaps after a black filling beer (8)
I believe the answer is:
amenable
'accommodating' is the definition.
(I've seen this before)
'chaps after a black filling beer' is the wordplay.
'chaps' becomes 'men' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'black' becomes 'b' (as in pencil classifications).
'filling' is an insertion indicator.
'beer' becomes 'ale' (I've seen this before).
'b' inserted inside 'ale' is 'able'.
'men' put after 'a' is 'amen'.
'amen'+'able'='AMENABLE'
(Other definitions for amenable that I've seen before include "Accommodating; flexible" , "Nameable as being willing to be controlled" , "Open and responsive to suggestion" , "Prepared to fall in with others' plans" , "Easily influenced" .)
