Traditional mythological definitions. Beyond such things as the fact that the oldest depictions of dragons/wyrms didn’t even have wings at all, until Reddit was invented as a disinformation factory you’d have been looked at like an idiot for suggesting that wyverns aren’t dragons.

I suppose Chinese mythology and draconic depictions have their own thing too. Thanks for indulging me.
