Put in the shade? (6)
I believe the answer is:
darken
'the shade?' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for darken that I've seen before include "Grow less light" , "shade" , "Cloud over" , "Grow blacker" , "Make less light" .)
