In addition coaster ferried in fruit (6)
I believe the answer is:
tomato
'fruit' is the definition.
(type of fruit)
'in addition coaster ferried' is the wordplay.
I cannot quite understand how this works, but
'coaster' could be 'mat' (I've seen this before) and 'mat' is found within the answer.
'in addition' could be 'too' (I've seen this before) and 'too' is found in the leftover letters.
No letters remain.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tomato that I've seen before include "A motto, oddly, for this fruit" , "Fruit-vegetable" , "Love apple (or "beef" fruit?)" , "Salad fruit or berry" , "Type of sauce" .)
