Vastupidiseks

Vastupidiseks is an Estonian translative form of the adjective vastupidine, meaning opposite or contrary. In grammatical terms, vastupidiseks denotes a change of state into being opposite, or into opposition, and is formed by adding the translative suffix -ksi to the stem vastupidine. The form is chiefly found in linguistic descriptions, grammars and dictionaries, and is less common in everyday speech, where other constructions are used to express opposition.

Etymologically, vastupidine combines the notion of being against or contrary with a descriptive stem, and vastupidiseks expresses the transition into that opposite state. The translative case -ksi signals becoming or turning into something, which explains the use of vastupidiseks in contexts describing process or transformation rather than a current attribute.

Usage notes: vastupidiseks is typically used with verbs of becoming, such as muutuma, or in predicative constructions that describe a state change. It is most common in linguistic or formal writing when illustrating how adjectives can take translative endings to express movement into a new qualitative state.

Examples: Ta muutus vastupidiseks varasemast seisukohast. (He became opposite to his previous stance.) Läbirääkimised muutusid vastupidiseks, kui pooled esitasid vastandlikud seisukohad. (The negotiations became oppositional as the parties presented opposing views.)

In summary, vastupidiseks is a specialized grammatical form used in Estonian to express turning into an opposite state, primarily within linguistic descriptions rather than everyday conversation. See also translatiiv, Estonian grammar, adjectives.
