Person stays for ages, feeling like a native (9)

'a native' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.

'person stays for ages feeling' is the wordplay.
I cannot really understand how this works, but
'ages' could be 'long' and 'long' is found within the answer.
'person' could be 'being' (I've seen this in other clues) and 'being' is present in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'like' is the link.

Can you help me to learn more?
