Today’s (first) glitch:
Alas, these teachers who gave the speaker such a love of the English language failed to instill an understanding of why we shouldn’t use a word if we don’t know what it means.
(As it says on a t-shirt, some people use big words just to make themselves sound more photosynthesis.)
Does your love of English embarrass or humiliate you when you read things online? No? Then you’re not mortified.
I’m not going to try to guess (no, that should not be try and guess, as if try and guess were separate actions) what the original writer intended, but I think appalled would be a good word with which to replace mortified. So would outraged — or annoyed, if a milder emotion is wanted.
“Thanks to the teachers who instilled in me such a love of English that I’m perpetually annoyed when reading the internet.”
(Technically, no one reads the internet itself; they read things on the internet.)
