Plonk second of toes into foaming Indian river (3,9)
I believe the answer is:
vin ordinaire
'plonk' is the definition.
(both can mean cheap wine)
'second of toes into foaming indian river' is the wordplay.
I cannot really understand how this works, but
'second' could be 're' (prefix meaning second in eg review, re-education) and 're' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
'into' could be 'in' and 'in' is found in the answer.
'river' could be 'r' (abbreviation) and 'r' 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 vin ordinaire that I've seen before include "Plonk" , "this isn't the best drink" , "Cheap table wine" .)
