Understanding autocorrect

[Italianblend]

Sometimes I just don't understand apple's autocorrect. Why is apple thinking that "go" is not a common word and what I want to write, especially after writing "if we." If we ago?

This certainly isn't the only circumstance, but is there any rhyme or reason to these autocorrects?

Possibly something you corrected at some point and it learned it thinking that's what you might usually mean.
