Questions & Answers about Isä rakensi eilen punaisen puutalon.
Why is the first part of the compound word puutalon in the nominative case (puu) instead of the genitive (puun)?
When the first part of a Finnish compound word describes the material something is made of, it stays in the basic nominative case. Therefore, puu (wood) + talo (house) correctly forms puutalo. If you used the genitive and wrote puuntalo, it would imply possession, literally meaning "the tree's house."
Since puutalon ends in -n, does that mean the whole compound word is in the genitive case here?
It looks identical to the genitive, but structurally it is the singular accusative case (often called the "total object" case). Because the action is completed—Dad built a whole house—the direct object takes the -n ending.
Why did the adjective punainen change to punaisen?
In Finnish, an adjective must agree in case with the noun it modifies. Since the object of the sentence (puutalon) is in the accusative case ending in -n, the adjective punainen (red) must also take the -n ending, changing its stem to punaise- and becoming punaisen.
Is it normal to put the time word eilen (yesterday) right after the verb? In English, it usually goes at the end.
Yes, it is very natural in Finnish. While Finnish word order is flexible, adverbs of time are frequently placed immediately after the verb. This establishes the time context early in the sentence, whereas putting it at the very end (Isä rakensi punaisen puutalon eilen) is also grammatically correct but places a slightly heavier emphasis on the time.
