Single fly on counter for fruit (8)
I believe the answer is:
tangelos
'for fruit' is the definition.
(I've seen this before)
'single fly on counter' is the wordplay.
'single' becomes 'sole' (similar in meaning).
'fly on' becomes 'gnat' (type of insect. I am not sure about the 'on' bit.).
'counter' says the letters should be written in reverse (counter can mean in the opposite direction).
'sole'+'gnat'='solegnat'
'solegnat' reversed gives 'TANGELOS'.
Can you help me to learn more?
(Another definition for tangelos that I've seen is " fruit".)
