Vessel in WC upended? Went out without relief in the end! (6)
I believe the answer is:
goblet
'vessel' is the definition.
(thesaurus)
'wc upended? went out without relief in the end' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'end' could be 'go' (going is a kind of ending) and 'go' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for goblet that I've seen before include "Large drinking cup" , "Drinking glass with stem and foot" , "Ornate glass" , "Stemmed drinking glass" , "Bowl-shaped drinking vessel" .)
