I look up words all the time to make sure I'm right about what they mean
Pre-internet it didn't matter: I could use ALL THE WORDS & if I was wrong, I could easily convince anyone that I was right bec look, who's gonna go & physically get a dictionary to prove I'm not?
NOBODY!

This tweet prompted by my use of 'penultimate'
As soon as I wrote it, it looked odd and I thought 'Hmmm. ARE YOU SURE?'
Yes, yes I am, thanks internet

Also, I have an English teaching degree, and yet, here we are, I'm looking up not-very-difficult words on the internet
Yes, that SHOULD scare the shit out of all y'all* :D
*'all y'all' is absolutely the correct usage, trust me on this
