Suitcase put away, say (5)
I believe the answer is:
state
'say' is the definition.
(synonyms)
'suitcase put away' is the wordplay.
'suitcase' becomes 'st' (I am not sure about this - if you are sure you should believe this answer much more).
'put away' becomes 'ate' (put away can mean to eat).
'st'+'ate'='STATE'
Can you help me to learn more?
(Other definitions for state that I've seen before include "Say; country" , "Civil government of a country" , "Condition of country." , "Public" , "whole people" .)
