Fruit drink company's rise covered by a volume (8)
I believe the answer is:
avocados
'fruit drink company's rise covered by a volume' is the definition.
I can't judge whether this defines the answer.
'drink company's rise covered by a volume' is the wordplay.
'drink' becomes 'soda' (soda is a kind of drink).
'company' becomes 'co' (abbreviation).
'rise' shows that the letters should be reversed in order.
'covered by' is a charade indicator (letters next to each other) (on top of in a down clue).
'volume' becomes 'v' (abbreviation for volume in book titles).
'soda'+'co'='sodaco'
'sodaco' reversed gives 'ocados'.
'a'+'v'='av'
'ocados' put after 'av' is 'AVOCADOS'.
Can you help me to learn more?
(Other definitions for avocados that I've seen before include "Large pulpy green fruits" , "Dark green pear-shaped fruits with creamy flesh" , "O Ava cods about the pears" , "'Pear' fruit" .)
