Parisian goes for smoke, maybe (6)
I believe the answer is:
vapour
'smoke maybe' is the definition.
(I know that smoking is a type of vapour)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for vapour that I've seen before include "Liquid in gas form" , "Visible steam or clouds" , "Particles suspended in air" , "Substance diffused in the air" , "Gas-like mist" .)
