näköisiin

Näköisiin is a Finnish grammatical suffix used to form the partitive plural of nouns and adjectives that end in certain vowel combinations. It is a form of the suffix -iin, which indicates the partitive case. The partitive case is used to express a part of something, an indefinite quantity, or an action that is ongoing or incomplete. The suffix -isiin is typically used after nouns and adjectives that end in diphthongs or certain vowel clusters. For example, the word "kaunis" (beautiful) becomes "kauniisiin" in the partitive plural, meaning "beautiful ones" or "some beautiful things." Similarly, "talo" (house) becomes "taloihin" (to houses), but if it were "kaunis talo" (beautiful house), the plural partitive would be "kauniisiin taloihin" (to beautiful houses).

The use of -isiin is a feature of Finnish grammar that helps to distinguish between different grammatical cases and numbers. It is important to note that not all nouns and adjectives take the -isiin ending in the partitive plural. The specific ending depends on the phonological structure of the word. For instance, words ending in a single vowel typically take different partitive plural endings. Understanding these variations is crucial for correct Finnish grammar. The partitive case itself has a wide range of uses in Finnish, including expressing the object of verbs that denote a partial action, such as "ostaa" (to buy) or "syödä" (to eat). Therefore, the -isiin ending plays a significant role in conveying nuanced meanings within Finnish sentences.
