On table, plan to swallow European drink (10)
I believe the answer is:
chartreuse
'drink' is the definition.
(Chartreuse is an example)
'on table plan to swallow european' is the wordplay.
I cannot quite see how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found in the answer.
'table' could be 'chart' (I've seen this before) and 'chart' is located in the answer.
'european' could be 'e' (abbreviation e.g. EU) and 'e' is present in the answer.
The remaining letters 'us' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chartreuse that I've seen before include "Carthusian liqueur" , "The spirit" , "Green-yellow liqueur" , "green liquid" , "drink" .)
