Heard dry grasses through the mist (4)
I believe the answer is:
haze
'the mist' is the definition.
(haze can mean a mist)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for haze that I've seen before include "State of mental confusion - mist" , "Film" , "Mistiness" , "Vapour" , "Mist or shimmer due to heat" .)
