Invective: An emotionally violent verbal denunciation or attack using strong, abusive language.
Example:
" Well,I'll learn her how to meddle. And looky here- you drop that school, you hear? I'll learn people to bring up a boy to put on airs over his own father and let on to be better'n what
he is. You lemme catch you fooling around that school again, you hear? Your mother couldn't read, and she couldn't write, nuther, before she died. None of the family couldn't, before
they died. I can't; and here you're a-swelling yourself up like this. I ain't the man to stand it- you hear?.."
(Huckleberry Finn, Pg.19-20)
This is an example of invective because Pap is trying to let Huck know that he will not tolerate him going to school. He feels like if he didn't know how to read then neither could he. His mom didn't know how to read, she died and she still coulnd't read. Therefore Pap felt like it was disrespectful to his mother's memory and he shouldn't go to school.
