Käsintehtyjen

Käsintehtyjen is a Finnish adjective-inflection form, specifically the genitive plural of the adjective käsintehty, which means handmade or handcrafted. In Finnish, adjectives agree with the nouns they modify in number and case, so when the noun is in genitive plural the adjective also takes a genitive plural form. Thus käsintehtyjen is used to describe or relate to a plural noun in genitive, such as in phrases referring to ownership or association with handmade items.

Common usage and examples:

- käsintehtyjen tuotteiden laatu — the quality of handmade products

- käsintehtyjen esineiden arvo — the value of handmade objects

For contrast, the partitive plural form käsintehtyjä is used when the noun is in partitive case, for example:

- käsintehtyjä tuotteita — handmade products (as a direct object in partitive)

Etymology and meaning:

The term arises from the compound käsin (by hand) and tehty (made), forming a closed compound meaning made by hand. As an attributive adjective, käsintehtyyn-type forms are used across contexts such as product descriptions, catalogs, and academic or journalistic writing, conveying a emphasis on craftsmanship without indicating a specific production method beyond “handmade.”

In summary, käsintehtyjen is the genitive plural form of the Finnish adjective meaning handmade, used to refer to handmade items in contexts requiring genitive agreement.
