Words and Sentences I Like In The Adventures of Huckleberry Finn

Classic book and very memorable, I particularly like some of the words and sentences used, some of which you don’t hear today.  Here are the ones that stood out to me with a rough guide on what they mean:

By and by = Over time
Muggins = a fool
Mud-cat = a catfish.
Rapscallions
Flapdoodle = Mess around
Spondulicks = Money
Considerable = A lot
Sivilize me = Civilise me
Sap-head = An idiot
Yellocution = Elocution
We’d allow it? 
I don’t take no stock in that
