You know, it pisses me off whenever I hear people saying “all words in the English language were made up, so why can’t we make new pronouns?” and “new words are made every day, why can’t people accept my bunself pronouns?” 

Let me nerd out for a hot second and teach you guys a little linguistics. There are two lexical categories. Words in the “open” classes are nouns, verbs, adjectives, and adverbs. It’s called open because new words are constantly added. I can make up a word right now, and as long as it has a meaning and is in an open class, people will be able to use it.

Then there’s the “closed” class. This includes prepositions, determiners, conjunctions, and yes, pronouns. Additions to the closed classes are very rare and difficult to grasp because they are part of the core of a language. You can’t just add things to a closed class because it just won’t work. It takes time to add or change things in closed classes, just look at how long it took for the singular “they” to become acceptable (and even then, it’s not entirely integrated into the English language yet).

That’s why trying to add new pronouns simply does not work.
