I started to read Mark Twain's book titled as "Adventures of Huckleberry Finn". At the very beginning of the book I came across with this sentence:
I never seen anybody but lied one time or another, without it was Aunt Polly, or the widow, or maybe the Mary.
Now I have two questions:
Is that "I never seen" part correct? Does it have anything to do with the dialect?
I cannot fully get the meaning of the sentence; Would you please tell me the meaning of the sentence in plain English. Particularly, I have problem with the "but" and "without it" parts.
