You don't need to type special Estonian letters correctly.
Type o instead of õ or ö, and still find the right word.

You also don't need to know the exact form of the word.
Estonian has 14 cases, so one word can appear in many forms.

For example, if you type oe, the dictionary can understand that you may mean õe, and guide you back to õde, meaning sister.

Type what you remember.
