One may hold a light tin container, drinking beer around bachelor (11)
I believe the answer is:
candelabrum
'one may hold a light' is the definition.
(a candelabrum holds candles)
'tin container drinking beer around bachelor' is the wordplay.
I cannot quite understand how this works, but
'tin' could be 'can' (synonyms) and 'can' is located in the answer.
'bachelor' could be 'b' (abbreviation e.g. BA=Bachelor of Arts) and 'b' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for candelabrum that I've seen before include "Lamp-holder" , "should be left hanging from the ceiling!" , "Holder for several lights" , "Source of light when lit" , "lamp holder" .)
