Like lemon chicken? (6)
I believe the answer is:
yellow
This clue could be a double definition.
'like lemon' is the first definition.
'yellow' can be an answer for 'lemon' (thesaurus). I am not certain of the 'like' bit.
'chicken?' is the second definition.
(as in cowardly)
Can you help me to learn more?
(Other definitions for yellow that I've seen before include "egg-hearted perhaps" , "Colour of cowardice, custard" , "like old paper" , "All looks it to the jaundiced eye" , "Colour of egg yolk and cowardice" .)
