Happened across an interesting bit of world-building in my social studies textbook that I thought I would share.

So for my World History class we have a textbook that I've found to be informative so far, but one portion of this textbook that I've found to be particularly interesting so far is that of the origins of the name "sabertoothed tigers" once we got to the topic of human origins. <br><br>The author of this book argues that given that the common name given to the ice age big cat, Smilodon Fatalis, is "sabertoothed tiger" this may cause confusion for people who are not familiar with it's appearance as these animals did not actually look like tigers, so he argues that a better name would be "sabertoothed cat." Anyways, I'm convinced at this point that the author of my textbook is a fellow worldbuilder, because what if in the world we're building "tiger" is simply the common name used to refer to any big cat in general. You could have lions, leopards, and jaguars that are native to an island instead of tigers, but they're referred to as tigers and tiger subspecies.
