T-Rex: In English we call bears "bears".
T-Rex: Stay with me here.

T-Rex: But if you go back in the language far enough, there's different names for these animals!

T-Rex: Go back all the way to Proto-Indo-European, an early ancestor to English that's now lost because nobody thought to ever write it down or also invent writing, and you can see "bear"'s connection to words for things like "brown" and "wild animal".

Utahraptor: But not to concepts of "bear"?
T-Rex: Nope!! That's "rtko".

T-Rex: And while this early "bear" root survived into Greek ("arktos") and Latin ("ursus"), the northern people didn't want to say "rtko" because they thought using the bear's TRUE name would summon it!! So they used a euphemism like "the brown one" which sounded like "bear" and now we call bears "bears".

Off panel: So if we were to speak a bear's TRUE name, they'd appear and eat us all?
T-Rex: Nah. Rtko rtko rtko. See? We're fine!
T-Rex: Also we're DINOSAURS and we fear not the bear??
