She->her (like everything in English) makes a lot more sense if you start in the roots of English. She was “hio” or “heo” and her was “hire”. By the 13th century, the pronunciations of he and heo had converged and become synonyms so “she” was introduced.

She shares a letter with seo, which was the root of both he and heo.

Simple pattern matching really can’t work in English - the roots are way too messy. And it’s absolutely amazing that people can become reasonably fluent if they only start learning as adults.
