Inner locative cases in Estonian

Estonian has three types of case forms that indicate location with reference to the interior of something.

1. Illative case - movement into something. It answers the questions 'where to?' and 'whither?'.
2. Inessive case - location inside something. It answers the question 'where?'.
3. Elative case - movement out of something. It answers the questions 'where from?' and 'whence?'.

The case endings (-sse, -s, -st) that express these concepts are comparable to certain prepositions in English, but they are added to the end of the genitive form in Estonian:

1. Illative: majasse = into the house
2. Inessive: majas = in the house
3. Elative: majast = from the house
