korkealaatuisissa

Korkealaatuisissa is the inessive plural form of the Finnish adjective korkealaatuinen, meaning high-quality. It is used to describe nouns in the plural when the sense is “in high-quality [things]” or “in high-quality ones.” In English this corresponds to phrases like “in high-quality items” or “in high-quality products.” The form arises from the stem korkealaatu- with the adjective ending -inen and the plural inessive ending -issa/-issä, here as -is-sa.

In usage, korkealaatuisissa is typically placed before a plural noun in the inessive case, or it can appear in a clause referring to a context or state related to quality. It is common in descriptions, evaluations, marketing texts, and reviews where a group of items or materials is characterized by high quality. Examples of common collocations include korkealaatuisissa tuotteissa (in high-quality products), korkealaatuisissa materiaaleissa (in high-quality materials), and korkealaatuisissa palveluissa (in high-quality services).

Examples:

- Korkealaatuisissa tuotteissa on usein käytössä pidempi takuuaika.

- Yrityksemme panostaa korkealaatuisissa rakennusmateriaaleissa, jotta lopputulos kestää pitkään.

Notes:

Korkealaatuisissa is not a standalone noun; it is an adjective in the inessive plural that modifies a noun. For general statements about quality, Finnish often uses korkealaatuinen (singular) or korkea laatutaso (high level of quality), while korkealaatuisissa emphasizes a plural context or setting.
