Tästä

Tästä is a Finnish grammatical form of the demonstrative pronoun tämä (this). It is the elative singular form, meaning “from this,” “out of this,” or “of this.” It indicates origin, source, basis, or reference point in a statement or clause.

In usage, tästä appears after verbs or in prepositional phrases to link a reference point to what is being described. Common expressions include:

- Tästä alkaa tarina. (A story begins from this / from here this story begins.)

- Tästä on kyse. (This is what it’s about.)

- Tästä lähtien / Tästä eteenpäin. (From this point on / forward from here.)

- Tästä syystä. (For this reason.)

Grammatically, tästä is the elative case form of demuestraive tämä. The elative case in Finnish often expresses movement away from a source or a basis for a statement. Because it is a case form, tästä cannot stand alone as a bare pronoun; it functions with a finite verb or in a larger phrase.

Etymology and related forms: tästä derives from the demonstrative root tämä with the elative suffix -stä, following Finnish vowel harmony rules. Related forms of this demonstrative appear in other cases and in related demonstratives like tuo (that) and se (that/it), each with its own elative form (tuosta, siitä, etc.).

Notes: Tästä is frequent in written and spoken Finnish, especially in expository or argumentative contexts, where speakers reference the starting point, cause, or subject under discussion. It is also common in compound expressions that mark progression or justification.
