päinvastaisia

Päivinvastainen (päinvastainen) is a Finnish adjective meaning opposite, contrary or reverse. Päinvastaisia is the plural form used to describe several things that are opposite or inverse relative to a reference point.

In everyday language, päinvastaisia describes opposing viewpoints, directions, conditions or characteristics. Common collocations include päinvastaisia väitteitä (opposite/contrary claims), päinvastaisia reittejä (opposite routes) and päinvastaisia ratkaisuja (opposite solutions). In philosophy and rhetoric, the term signals a contrast between positions or arguments. In linguistics, it relates to antonyms, although the standard term for a word with opposite meaning is antonyymi.

In mathematics and logic, more precise terms such as käänteinen (inverse) or vastainen are often preferred. Nevertheless, päinvastainen can appear in broader or non-technical Finnish to describe inverse relationships or negations in less formal writing, depending on the author and context.

Grammar: päinvastaisia is the plural form of the adjective when modifying a plural noun in partitive or other cases where the plural form requires -isia. For example, päinvastaisia väitteitä means “opposite/contrary claims.” The exact endings can vary with the noun and case, but the meaning remains focused on opposition or reversal.
