Arrangement of chairs, first put out for dining (6)
I believe the answer is:
eating
'dining' is the definition.
(I've seen this in another clue)
'arrangement of chairs first put out' is the wordplay.
'arrangement of chairs' becomes 'seating' (arranging seats).
'first put out' means to remove the first letter.
'seating' with its first letter taken off is 'EATING'.
'for' acts as a link.
(Other definitions for eating that I've seen before include "at breakfast?" , "Having supper?" , "Ingestion" , "Taking in solid food" , "Consuming food" .)
