I can’t recall if other systems have it. They must, considering your difficulty.
iPad and iPhone have it under Setting-General-Keyboard.

P.S. when I type b rillig as one word I get “‘Twas brillig and the slythy toves did gyre and gimbal in the wabe. All mimsy were the borogoves and the mome raths out grabe. "
Autocorrect very much gets in my way, and spellcheck keeps me on my toes.
Tweaking autocorrect is useful when a long word or term is going to be used repeatedly. For example, if you’re writing about the Smithsonian Institution, you can set autocorrect to change “tsi” to the full name. Saves time and effort, but you have to remember to delete it from the list when you’ve finished. I made use of this feature just a couple of weeks ago to avoid having to write out a long company name that appeared throughout a document.
I never use either autocorrect, or spellcheck, but yeah, autocorrect is a much worse bane. I write so creatively (in my native tongue) that autocorrect simply cannot follow, or cope, and works as well as bricks thrown randomly onto a figure skater’s path. I’m also an excellent speller (again in my mother language), so a spellcheck is useless. But I use neither even when writing in English, or other school-learned languages.
