energisiin

energisiin is the illative plural form of the Finnish adjective energinen, meaning energetic. It is used to modify plural nouns in the illative case, indicating movement toward or into groups, things, or concepts described as energetic. The form appears when the noun being described is in its illative plural, such as into energetic groups or into energetic plans.

Morphology and related forms: energinen is the base adjective. Common related forms include energisen (genitive singular), energistä (partitive singular), energisiä (partitive plural), energiset (nominative plural). The illative singular is energiseen, while the illative plural is energisiin. Finnish adjectives inflect to agree with the noun they modify across cases and numbers, so energisiin appears specifically when both the adjective and its noun are in plural illative.

Usage notes: energisiin is relatively rare in everyday speech compared with other ways to express energy or activity, but it can be found in written or formal Finnish describing groups or activities perceived as energetic. It typically occurs with plural nouns in illative constructions, such as energisiin ryhmiin (into energetic groups) or energisiin suunnitelmiin (into energetic plans). In many ordinary contexts, speakers might use energiset to describe energetic groups in the nominative plural or use different phrasing to avoid illative plural complexity.
