Where Parisians are two thirds poorly? (4)
I believe the answer is:
orly
'where parisians' is the definition.
The definition suggests a singular noun which matches the answer.
'two thirds poorly?' is the wordplay.
'ORLY' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.
'are' acts as a link.
Can you help me to learn more?
(Other definitions for orly that I've seen before include "Paris airport" , "Parisian airport" , "French airport" .)
