I believe the answer is:

haloes

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

'circles' is the definition.
The answer and definition can be both shapes as well as being plural nouns.
Perhaps there's an association between them I don't understand?

'he also goes round' is the wordplay.
'goes round' is an anagram indicator.
'he'+'also'='healso'
'healso' with letters rearranged gives 'HALOES'.

'in' acts as a link.

Can you help me to learn more?

(Another definition for haloes that I've seen is " Circles over saints".)
