Colour of Manx cat eaten by rats? (9)
I believe the answer is:
vermilion
'colour' is the definition.
(I know that vermilion is a colour)
'of manx cat eaten by rats?' is the wordplay.
'of manx' means to remove the last letter (I've seen 'manx' mean this (Manx cats have no tail)).
'cat' becomes 'lion' (lion is a kind of cat).
'eaten' is an insertion indicator.
'by rats?' becomes 'vermin' (rats are vermin. I am not sure about the 'by' bit.).
'lion' with its final letter taken off is 'lio'.
'lio' going into 'vermin' is 'VERMILION'.
Can you help me to learn more?
(Other definitions for vermilion that I've seen before include "shade" , "Vivid red colour" , "Brilliant red" , "Bright scarlet" , "Vivid red (with an orange tinge?)" .)
