Why do we sometimes say a word or look at a word so many times that it sounds foreign/doesn’t look like a real word?

Question

I hope this makes sense

Like when you’re taking notes and you write a word and it just doesn’t seem spelled correctly no matter what or it just seems strange, or when you say a word and it feels weird coming out and you have difficulty comprehending that it’s an actual word.

Words are ultimately arbitrary, there’s no particular reason for any given word to have a given meaning other than at some point, enough people agreed on it.

Onomatopoeia are somewhat of an exception, but most words have no intrinsic meaning.
