Take Crosophile to court after upset? It makes you sick (6)
I believe the answer is:
emetic
'it makes you sick' is the definition.
(an emetic medicine makes you sick)
'take crosophile to court after upset?' is the wordplay.
I cannot really understand how this works, but
'crosophile' could be 'me' (where the crossword setter is 'Crosophile') and 'me' is present 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 emetic that I've seen before include "Medicine to make you sick" , "Medicine taken to make one vomit" , "making you throw up" , "Cite me as containing sick-making substance" , "Purgative" .)
