Food bound to be consumed by traveller under pressure (9)
I believe the answer is:
provender
'traveller under pressure' is the definition.
I can't judge whether this definition defines the answer.
'food bound to be consumed' is the wordplay.
'food bound' becomes 'prover' (I can't explain this - if you can you should believe this answer much more).
'to be' becomes 'end' (ending is a kind of being).
'consumed' means one lot of letters goes inside another.
'prover' placed around 'end' is 'PROVENDER'.
'by' acts as a link.
Can you help me to learn more?
(Other definitions for provender that I've seen before include "Dry feed" , "Dry food for beasts" , "animal feed" , "Animal fodder" .)
