Tämäntyyppisiä

Tämäntyyppisiä is a Finnish grammatical form that functions as a determiner phrase meaning “of this kind” or “such kinds.” It is used to refer to items that belong to the same category or type as something previously mentioned or implied. The phrase is most commonly used to modify a noun in the partitive plural, as in the sentence: töissä on tämän tyyppisiä asioita or, in fused form, tämäntyyppisiä asioita, meaning “such kinds of things.”

Formation and morphology: The base elements are the demonstrative tämä (“this”) and the adjective tyyppinen (“type” or “kind”). In this expression, nämä elements combine in the genitive form of tämä, yielding tämän, and the plural partitive form of the adjective, tyyppisiä. The result is typically written as yksi word, tämäntyyppisiä, although a spaced form, tämän tyyppisiä, is also correct in some contexts. The construction agrees with the head noun in number (plural when describing multiple items).

Usage: Tämäntyyppisiä is common in descriptive or analytical writing, including journalism, reports, and academic prose, where categories or examples are described or contrasted. Examples include: “Tämäntyyppisiä ongelmia esiintyy useissa projekteissa” (“There are problems of this kind in several projects”) and “Tämäntyyppisiä tuotteita ei ole esillä nyt” (“Products of this kind are not on display now”). The phrase specifically signals a reference to a defined set or class of items.

Variants and related expressions: Other ways to convey a similar meaning include tällaista, tällaisia, or tämänlaatuinen/tämänlaatuista, which can express “such” or “this kind of” with different syntactic requirements or nuances. The choice depends on the noun, case, and number being described.
