Noticeably wet coat? (5)
I believe the answer is:
paint
This could be a double definition.
'noticeably wet' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'coat?' is the second definition.
(paint is a kind of coat)
Can you help me to learn more?
(Other definitions for paint that I've seen before include "Daub" , "Coloured liquid in tins" , "Item used by 23 Across" , "Catch a likeness" , "Use a brush on canvas" .)
