Great mob chucked fruit (8)
I believe the answer is:
bergamot
'fruit' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'great mob chucked' is the wordplay.
'chucked' indicates an anagram (letters chucked around).
'great'+'mob'='greatmob'
'greatmob' with letters rearranged gives 'BERGAMOT'.
Can you help me to learn more?
(Other definitions for bergamot that I've seen before include "Oil from a citrus fruit used to flavour Earl Grey tea -- to grab me (anag)" , "perfume" , "Oily substance extracted oranges, used in Earl Grey tea" , "Kind of orange - great mob (anag)" , "Something extracted from orange" .)
