Brightly coloured carpet inlaid in addition (6)
I believe the answer is:
tomato
'brightly coloured carpet inlaid in addition' is the definition.
I can't judge whether this defines the answer.
'carpet inlaid in addition' is the wordplay.
I cannot really understand how this works, but
'carpet' could be 'mat' (a mat is a floor covering) and 'mat' is present in the answer.
'in addition' could be 'too' (I've seen this in another clue) and 'too' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tomato that I've seen before include "A motto turned out to be fruit/veg" , "A motto, strangely, for this fruit" , "It used to be call a love-apple" , "Love apple (archaic)" , "It's also known as a love apple" .)
