Always opens containers holding energy drinks (9)
I believe the answer is:
beverages
'drinks' is the definition.
('beverage' can be a synonym of 'drink')
'always opens containers holding energy' is the wordplay.
I cannot quite understand how this works, but
'always' could be 'ever' ('ever' can be a synonym of 'always') and 'ever' is found within the answer.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is located in the answer.
'containers' could be 'bags' (bag is a kind of container) and 'bags' is present in the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beverages that I've seen before include "Drinks" , "Vegas beer (anag) - beer etc" .)
