what does นั้น mean in terms like ฉันนั้น เธอนั้น
I know นั้น itself means "there, that". But I found terms like ฉันนั้น เธอนั้น showing up in lyrics very often. I'm trying to understand it basically works as a add-on of the pronoun? To make things sound more... emotional, with a deeper connection or poetic?
I think only natives can explain this well...?
