Pause quickly for something to eat (9)
I believe the answer is:
breakfast
'something to eat' is the definition.
(breakfast is a kind of food)
'pause quickly' is the wordplay.
'pause' becomes 'break' (synonyms).
'quickly' becomes 'fast' (synonyms).
'break'+'fast'='BREAKFAST'
'for' acts as a link.
(Other definitions for breakfast that I've seen before include "One could be first on the table" , "First meal of the day" , "beginning to day" , "something to eat" , "See 24" .)
