"This one is incorrect and that one is correct."
Translation:Tämä on väärin ja tuo on oikein.
"Väärä" and "oikea" are adjectives whereas "väärin" and "oikein" are adverbs. Unlike English, Finnish uses adverbs instead of adjectives in predicatives about whether something factually or morally wrong/right. Predicatives like this are therefore referred to as predicative adverbials, which isn't a thing in English grammar.
