i’m so upset
I just realized that the reason ghosts say Boo! is because it’s a latin verb
they’re literally saying ‘I alarm/I am alarming/I do alarm!!
if it comes from the latin word, they’re actually saying “I’M YELLING!” which is even cuter
Actually it looks like boo and boō probably aren’t related, and boo probably came from Scotland. One theory is that it was an imitation of the cry of a calf.
Sometimes linguistics is an adventure. Sometimes it’s a wet blanket. Che sarà, sarà.
