#11: The word “butterfly” used to be “flutterby.”
This one is a bit of a misnomer, but it’s a fun fact, nonetheless! Though the word “butterfly” comes from the Old English word “buttorfleoge” meaning butterfly, children used to switch the consonants around to pronounce it as “flutterby.” The word is so endearing and true to what a butterfly actually does, sources on the internet seem to think that this was once the official term!
