Individual copies turned over with speed (8)
'individual' is the definition.
'copies turned over with speed' is the wordplay.
'copies' becomes 'apes' ('ape' can be a synonym of 'copy').
'turned over' shows that the letters should be reversed in order.
'with' says to put letters next to each other.
'speed' becomes 'rate' (the speed at which something happens).
'apes' reversed gives 'sepa'.
'sepa'+'rate'='SEPARATE'
(Other definitions for separate that I've seen before include "Divide, keep apart" , "Individual and distinct" , "Come apart" , "Distinct, not joined" , "Move" .)
'individual' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'copies turned over with speed' is the wordplay.
I cannot quite understand how this works, but
'over' could be 're' and 're' is found within the answer.
'with' could be 'w' (abbreviation) and 'w' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
