ex) How nice of you to say so!
Whatis the part of speech of 'so' in the sentence? Is is an adverb or a pronoun?
English Grammar -
It looks like an adverb, but it is acting like a pronoun. In that sentence, "so" is referring to whatever the other speaker has already said.
I'd say it's more of a pronoun than and adverb.
