Hounds prepare to travel (4)
I believe the answer is:
pack
'prepare to travel' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for pack that I've seen before include "Wolves, say" , "Stuff - rucksack" , "Group of scouts" , "Set of cards or wolves" , "Parcel" .)
