It makes one throw up turns to cite me (6)
I believe the answer is:
emetic
'it makes one throw up' is the definition.
The definition suggests a singular noun which matches the answer.
'turns to cite me' is the wordplay.
'turns' shows that the letters should be reversed in order.
'cite'+'me'='citeme'
'citeme' in reverse letter order is 'EMETIC'.
Can you help me to learn more?
(Other definitions for emetic that I've seen before include "Class including frogs, toads, newts, etc" , "Medicine to make you sick" , "Vomit-inducing medication" , "Medicine taken to make one vomit" , "Nauseating" .)
