Fruit also put round floor covering (6)
I believe the answer is:
tomato
'fruit' is the definition.
(type of fruit)
'also put round floor covering' is the wordplay.
'also' becomes 'too' (synonyms).
'put round' is an insertion indicator.
'floor covering' becomes 'mat' (a mat is a floor covering).
'too' placed around 'mat' is 'TOMATO'.
(Other definitions for tomato that I've seen before include "In France, it's a love apple" , "Shiny red fruit" , "Type of sauce" , "that's suitable to eat" , "A motto turned out to be fruit/veg" .)
