Suitcase for characters up for taking a break (3)
I believe the answer is:
bag
'suitcase' is the definition.
('bag' can be a synonym of 'suitcase')
'taking a break' is the wordplay.
'taking' means one lot of letters goes inside another.
'break' becomes 'bg' (I am not sure about this - if you are sure you should believe this answer much more).
'a' going into 'bg' is 'BAG'.
'for characters up for' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for bag that I've seen before include "Valise" , "Claim" , "Quantity of game shot in a particular period" , "Container for holding or carrying" , "Pouch" .)
