One creates a stink? On the contrary! (9)
I believe the answer is:
deodorant
'the contrary' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'one creates a stink?' is the wordplay.
'one creates' becomes 'de' (I can't justify this - if you can you should believe this answer much more).
'a stink?' becomes 'odorant' (I've seen this before).
'de'+'odorant'='DEODORANT'
'on' is the link.
Can you help me to learn more?
(Other definitions for deodorant that I've seen before include "Body odour neutraliser" , "Smell masker" , "Remover of smells" , "Underarm protection?" , "Substance that removes unwanted smells" .)
