Listen up, dragons have 4 legs. Wings aren't important. When they do have wings it's usually on their back.
Wyvrens, however, always have wings as their front limbs, and only only have two legs. A lot of people get it wrong because nobody gives any absolute fuck about fantasy anatomy, but this is the defining traits of both regardless of what medium portrays it as.
The defining traits of an Ettin is that it is a giant with two heads. Some games and stories portray it as just a giant, some portray it as just a guy with two heads, but that just means those stories took liberties with it and are wrong.
That said, even trolls and goblins have a far stricter adherence to what constitutes as a troll or goblin in design than dragons do. Because it's entirely fantasy it's basically just a meme in the actual sense of the word and as such varies in interpretation from person to person, culture to culture, but still adheres to some common idea of what constitutes it as what it is.
As another example, there are many different varieties of Pepe yet you know instantly that each one is a Pepe. What constitutes as a requirement for it to be Pepe? The colors? Being a frog? The hand gestures they make? There are variations which do not match any of those things and yet the person posting it is still a dumb frog poster.
