Crossword Genius

One speaks ill of Cypriots, for example (9)

Ross

I believe the answer is:

islanders

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

'speaks ill of cypriots for example' is the definition.
I can't judge whether this definition defines the answer.

'one' is the wordplay.
I cannot really understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for islanders that I've seen before include "Snares lid (anag.)" , "people living in detached territories" .)
