Higher following small meal (6)
I believe the answer is:
supper
'meal' is the definition.
(I know that Supper is a type of meal)
'higher following small' is the wordplay.
'higher' becomes 'upper' (higher up).
'following' means one lot of letters go next to another.
'small' becomes 's' (abbreviation - e.g. clothes size).
'upper' put after 's' is 'SUPPER'.
(Other definitions for supper that I've seen before include "Evening repast" , "has one had a few drinks?" , "Light, late, meal" , "Late repast" , "consumer" .)
