täydellisiin

Täydellisiin is the illative plural form of the Finnish adjective täydellinen, meaning complete or perfect. In Finnish, adjectives agree with the nouns they modify in number and case, and when the noun is plural and in the illative case, the adjective takes the suffix -isiin. Thus täydellisiin is used with plural nouns in illative, signaling movement toward or into “perfect” objects or concepts.

Morphology and formation: The base adjective täyde that appears in käytännössä the stem täydell- combines with the illative plural suffix -isiin to produce täydellisiin. This pattern is common for adjectives ending in -ellinen, where the illative plural form often ends in -isiin. Put simply, täydellisiin describes plural nouns that are in the illative case and are endowed with the attribute “perfect/complete.”

Usage: Täydellisiin is used in contexts where a plural noun is in illative and is described as perfect or complete. Common examples include täydellisiin suunnitelmiin (into perfect plans) or täydellisiin vastauksiin (into perfect answers). The form is primarily encountered in written Finnish, including descriptive, instructional, or literary prose, and appears in grammatical explanations illustrating Finnish adjective declension.

Notes: Täydellisiin is not a standalone noun; it is a morphologically inflected form of täydellinen. When looking up the word in dictionaries, one would find the base form täydellinen, with inflected forms like täy del lliisiin provided as part of the adjective’s paradigm. The illative plural form interacts with nouns in illative to convey direction into plural, perfect-described items. See also Finnish adjectives, illative case, and adjective declension.
