Questions & Answers about Hänen käsin tehty laukkunsa on nahkaa.
Why is the word order käsin tehty laukkunsa instead of putting käsin after the noun?
This is the core rule for complex participial attributes. When a participle like tehty (made) describes a noun like laukku (bag), any words that give more information about the participle itself must be placed strictly and directly before it. So, käsin (by hand) goes right before tehty, creating the neat modifier package käsin tehty (handmade) before the main noun.
How does the possessive structure work with a long modifier in the middle?
The core possessive structure here is Hänen laukkunsa (His bag). The genitive pronoun Hänen comes first, and the possessive suffix -nsa attaches to the main noun. Any adjectives or participle phrases, like käsin tehty, are simply sandwiched in the middle. The possessive suffix never attaches to the modifiers.
What form is the word käsin?
It is in the instructive case. This case is relatively rare and mostly used in fixed expressions to explain how or with what instrument something is done. It is formed using the plural stem plus -n, so käsin literally means with hands or by hand.
Why is nahkaa (leather) in the partitive case?
When you state what material an object is made of using the verb olla (to be), the material noun acts as a predicative and must be in the partitive case. Saying on nahkaa translates to is made of leather.
