Note the various pears at the greengrocer’s (6)
I believe the answer is:
grapes
'at the greengrocer's' is the definition.
I can't judge whether this definition defines the answer.
'note the various pears' is the wordplay.
'note' becomes 'g' (musical note**).
'the various' is an anagram indicator.
'pears' anagrammed gives 'rapes'.
'g'+'rapes'='GRAPES'
Can you help me to learn more?
(Other definitions for grapes that I've seen before include "Juicy fruits" , "John Steinbeck wrote 'The . . . . . . of Wrath'" , "Fruit that grows in clusters" , "They grow on vines" , "Fruit for wine" .)
