Take a bit for the horse (7)
I believe the answer is:
snaffle
I believe this is a double definition.
'take' is the first definition.
(snaffling is a kind of taking)
'a bit for the horse' is the second definition.
(I've seen this before)
(Other definitions for snaffle that I've seen before include "Capture" , "Pinch" , "A bit; to grab for oneself" , "Appropriate" , "Horse's bit" .)
