Painter might open the door? It’s dried (6)
I believe the answer is:
raisin
'painter' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for raisin that I've seen before include "An iris (anag)" , "fruit product" , "Partially dried grape" , "A dried grape, nice in cake" , "Somewhat dry fruit" .)
