vastakohtaisiin

Vastakohtaisiin is a Finnish inflected form of the adjective vastakohtainen, meaning "opposite" or "antonymous." It represents the illative plural form used when a noun it modifies is in the illative case, typically in phrases referring to "to the opposite X" such as vastakohtaisiin käsitteisiin (to opposite concepts) or vastakohtaisiin sanoihin (to opposite words). In practice, vastakohtaisiin appears mainly in linguistic descriptions, dictionaries, and academic writing, rather than in everyday speech.

The form is part of Finnish morphology, where adjectives agree with the noun in number and case. The base adjective vastakohtainen combines with the plural illative ending -iin (and the stem may insert -aisiin for certain nouns). The full form thus signals both plurality and illativeness in one word.

Common related terms include vastakohta (antonym), vastakohtainen (antonymous/opposite), and vastakohdat (antitheses; opposites). The term is not typically used standalone; rather, it functions as a descriptor within noun phrases.
