Questions & Answers about Tämä puutalo on meidän.
Why is the first part of puutalo in the nominative case (puu) rather than the genitive case (puun)?
When the first part of a compound noun describes the material that the second part is made of, it stays in the nominative case. So, puutalo means a house made of wood. If the first word expressed a target or purpose, it would typically be in the genitive (like lastenhuone, a room for children).
Why is meidän in the genitive case here?
In Finnish, possession is expressed using the genitive case. While meidän often translates to 'our' when placed before a noun, here it stands alone after the verb on to mean the standalone possessive pronoun 'ours'.
If meidän indicates possession, why isn't there a possessive suffix used in this sentence?
Possessive suffixes are only attached to the 'owned' thing (the noun), never to the pronoun itself. If you said 'This is our wooden house', it would be Tämä on meidän puutalomme, attaching -mme to the noun. Because the noun puutalo comes before the verb and meidän stands alone at the end ('is ours'), no suffix is triggered.
How does the meaning change if I say Tämä on meidän puutalomme instead of Tämä puutalo on meidän?
