Maastasi

Maastasi is a Finnish grammatical form that means “from your terrain” or “out of your land.” It is formed by taking the ablative stem maasta (from the land/ground) and adding the second-person singular possessive suffix -si, producing maastasi. The form marks origin or source that is associated with the person being addressed.

In usage, maastasi is used to refer to things located on or connected to someone’s land or surroundings, often in contexts discussing land use, property, or environmental features tied to the listener. The sense can be literal, referring to physical terrain, or metaphorical, describing someone’s personal environment or surroundings. In everyday speech, similar ideas can also be expressed with other constructions, such as alternatives that emphasize the listener’s property or area.

Maastasi belongs to a broader set of Finnish forms that combine a case ending with a possessive suffix to indicate source or relation relative to the speaker and listener. Related forms include maastani (from my terrain) and maastanne/maastanne (from your terrain, plural or formal you), illustrating the same possessive-case pattern across different persons.

Notes:

- Maastasi is most common in linguistic descriptions of Finnish morphology and in contexts where precise attribution of origin to the listener is needed.

- It should not be confused with maasta, which simply means “from the land/ground” without specifying possession.
