isolates

I'm a little stuck... Click here to teach me more about this clue!

'identifies' is the definition.
Although both the answer and definition are verbs in their -s form, I don't see how they can define each other.

'aisles to change' is the wordplay.
'change' is an anagram indicator.
'aisles'+'to'='aislesto'
'aislesto' anagrammed gives 'ISOLATES'.

Can you help me to learn more?

(Other definitions for isolates that I've seen before include "Oils seat (anag.)" , "Places apart or alone" , "Keeps apart from others" , "Sets apart from others" .)
