Ypots, also known as
yping terrors just mean
typos (typographic errors) or
typing errors.
Frequently when you are typing, your fingers get ahead of your brain (or the other way around?). The result is a typo such as "teh" for "the". Most common spelling errors are ypots (when your brain knows the spelling of the word but your hand doesn't follow), or spell error (when your brain doesn't really know the correct spelling).
Malagasy Online Spell Checker can show you such spelling errors, but only if the misspelled is a
false negative.
