At the end of the year worker meets the late British monarch to present ornamental crystal vessel, perhaps (8)
I believe the answer is:
decanter
'british monarch to present ornamental crystal vessel perhaps' is the definition.
I can't tell whether this defines the answer.
'at the end of the year worker meets the late' is the wordplay.
'at the end of' indicates one should take the final letters.
'year worker' becomes 'canter' (I am not sure about this - if you are sure you should believe this answer much more).
'meets' is a charade indicator (letters next to each other).
'the late' becomes 'd'.
The last letter of 'the' is 'e'.
'e'+'canter'='ecanter'
'ecanter' after 'd' is 'DECANTER'.
Can you help me to learn more?
(Other definitions for decanter that I've seen before include "Stoppered wine bottle" , "glass full of drink" , "Bottle with a stopper for wine" , "Stoppered liquor container" , "Vessel with stopper for serving wine" .)
