menestyksekkäisiin

Menestyksekkäisiin is a Finnish inflected form of the adjective menestyksekäs, meaning “successful.” It is the illative plural form, used to modify a plural noun in illative case, which in Finnish marks movement toward or into something. In practice, the form appears in phrases such as menestyksekkäisiin suunnitelmiin (to the successful plans) or menestyksekkäisiin yrityksiin (to the successful enterprises). The corresponding nominative plural is menestyksekkäät, while the illative plural ends with -isiin, yielding menestyksekkäisiin. The stem remains menestyksek- with appropriate ending changes to agree with case and number.

Usage notes: Like other Finnish adjectives, menestyksekkäisiin must agree with the noun it describes in number and case. The illative plural form is relatively formal and more common in written language or careful speech. In everyday prose, speakers may instead use phrases where the adjective appears in other cases or where the noun is given in a different form, for example with a genitive or partitive noun.

Etymology and meaning: The word derives from the noun menestys (success) plus the derivational suffix -käs, producing a term meaning “characterized by success.” As an inflected form, menestyksekkäisiin does not constitute a separate lexical entry but demonstrates Finnish adjective agreement and case structure.
