Questions & Answers about Asiantuntija ei koskaan erehdy alkuperäisestä teoksesta.
Why is alkuperäisestä teoksesta in the elative case (-sta/-stä)?
The verb erehtyä (to be mistaken, to err) has a strict rection: it requires the thing you are mistaken about to be in the elative case (-sta/-stä). This aligns with the lesson's theme of verbs expressing separation, distinction, or source taking the elative.
Why is the verb form erehdy and not erehty?
Erehtyä is a type 1 verb subject to consonant gradation. In the negative present tense, we use the weak stem (the 'minä' form minus the 'n'). The consonant cluster -ht- weakens to -hd-, giving us ei erehdy.
What is the base form of teoksesta, and why does it have that -kse- in the middle?
The base noun is teos (a work, such as a piece of art or literature). Finnish words ending in -os or -ös belong to a specific word type where the stem changes to add -kse- before case endings, so teos becomes teokse- + -sta.
