What dictionary does your iPad browser use?

Let’s say its safari. Regardless, my question pertains to the fact that auto correct seems to be weird; fluther, a word in English like gaggle or herd changes automatically to flutter, with many more examples where that came from.

Why does the feature assume you mean something else, when the word you have typed is a perfectly good one.

Names notwithstanding, shouldn’t the correct feature not suggest anything if the word is in the oxford fucking dictionary?

Why do I constantly have to double click on every other word, not to mention names which can be exotic, phonetic or foreign?

I could turn it off, I know, this is not what I’m asking.

Bonus lure if you can explain to me, here or in IM, how to quote teach my autocorrect names, words I prefer spelt a certain way and what have you.

Thanks collective, lurve on.
