Bishop gets loan for mixture (5)
I believe the answer is:
blend
'for mixture' is the definition.
(blend is a kind of mixture)
'bishop gets loan' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'gets' means one lot of letters go next to another.
'loan' becomes 'lend' (synonyms).
'b'+'lend'='BLEND'
(Other definitions for blend that I've seen before include "Amalgam" , "Combine together" , "Coalesce" , "Amalgamate" , "Merge" .)
