Fill beyond capacity on the day I eat out (7)
I believe the answer is:
'fill beyond capacity' is the definition.
(I've seen this in another clue)
'the day i eat out' is the wordplay.
'the day' becomes 'sat' (abbreviation for Saturday).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'eat' is an anagram of 'ate'.
'on' acts as a link.
(Other definitions for satiate that I've seen before include "Overfill - gorge" , "Have more than enough" , "Fill to satisfaction" , "Completely satisfy" , "Satisfy fully, cloy with excess" .)
