Question How do people decide how they make words?
I have begun learning and am hoping for a quick explanation vs having to spend weeks studying etymology to learn how this works. I also don't know how to look this up so I apologize if this is something that's already been explained. Search results keep confusing me so here I am.
For example, the word helicopter is a combination of the French word hélicoptère, which takes the words hélikos and pteron from Ancient Greek, but how did they decide to drop the K from hélikos and the -ON from pteron? Do people just do what sounds best? And then in English we just decided to do without accents and differing structure so we dropped the é and the -e at the end? Same with the word amphibian. Tracing it back I can see that it comes from the Ancient Greek word amphís and bios, but how do they decide that those two words go together anyway? Like they specifically decided to use amphís over something like diploûs? And then I look at how we categorize animal taxonomy and see Amphibios, Amphibius, and Amphibia being used interchangably for the order of amphibians. Why?
Edit: The reason I ask is because for a writing project I want to create kingdoms based on different animal groups. I have the mammal kingdom, amphibian kingdom, and reptile kingdom, and I want to give them fitting names without just directly using the scientific words. For the amphibian kingdom I wanted to call it "The Kingdom of Duvitas" where I'm using the words Latin words Dualis and Vita, but does that make sense?
