Way one is packed in a container — keep away (7)
I believe the answer is:
abstain
'keep away' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for abstain that I've seen before include "Refrain from doing something" , "Resist" , "Pass" , "Formally decline to vote" , "not come down on either side" .)
