Sorted, resorted and stocked (6)
I believe the answer is:
stored
'stocked' is the definition.
The answer and definition can be both to do with ownership as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'sorted resorted' is the wordplay.
'resorted' indicates anagramming the letters.
'sorted' anagrammed gives 'STORED'.
'and' is the link.
Can you help me to learn more?
(Other definitions for stored that I've seen before include "Stashed away" , "Kept for future use, as in warehouse" , "Kept for later use" , "Warehoused" , "Squirrelled away" .)
