Chaucer's regularly put in the shade (3)
I believe the answer is:
hue
'put in the shade' is the definition.
'hue' can be an answer for 'shade' (both can mean a colour). I'm not sure about the 'put in the' bit.
'chaucer's regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'chaucer' are 'HUE'.
Can you help me to learn more?
(Other definitions for hue that I've seen before include "complexion" , "'Pigment, colour (3)'" , "Cast" , "Tint, shade" , "General hubbub - . . . and cry" .)
