Questions & Answers about Heidän ideansa on epätieteellinen ja aivan epälooginen.
How does the prefix epä- work in epätieteellinen and epälooginen?
The prefix epä- acts exactly like the English prefixes "un-", "in-", or "il-". You attach it directly to the front of adjectives or abstract nouns to create their direct opposite. Here, looginen (logical) becomes epälooginen (illogical), and tieteellinen (scientific) becomes epätieteellinen (unscientific).
Do I need to change the vowels in epä- to match a word with back vowels, like looginen?
No, you don't. Words formed with the prefix epä- are treated like compound words, meaning vowel harmony applies to each part separately. The prefix always stays as epä-, and the original word keeps its own vowels. This is why epälooginen is allowed to have both front vowels (ä) and back vowels (o) in the same word.
Why is it heidän ideansa with the -nsa ending, instead of just heidän idea?
In standard written Finnish, when you use the third-person possessive pronouns hänen (his/her) or heidän (their), you must also add the matching possessive suffix to the noun itself. The pronoun heidän tells us whose idea it is, but grammar requires the -nsa suffix at the end of idea to make the structure complete.
