Questions & Answers about Tehtaan koneisto on uusi ja tehokas.
How is the word koneisto formed?
This is a perfect example of the current lesson. It is formed by taking the root word kone (machine) and adding the collective suffix -isto (a variant of -sto). Together, they mean a collection or system of machines: "machinery".
Why is the word for "factory" spelled tehtaan here?
This is the genitive (possessive) form, meaning "the factory's". The dictionary form is tehdas. When making the genitive, the stem becomes tehtaa-. This shows reverse consonant gradation, where the weak hd in tehdas changes to a strong ht before adding the -n ending.
The adjectives uusi and tehokas are in their basic forms. Shouldn't they match the genitive ending of tehtaan?
No, because they are describing the machinery (koneisto), not the factory (tehdas). Since koneisto is the subject of the sentence and is in the basic nominative case, the adjectives describing it stay in the nominative case too.
What is the root word of the adjective tehokas (efficient)?
It comes from the noun teho, meaning "power" or "effect". The suffix -kas (or -käs) is used to form adjectives that mean "having a lot of" a certain quality. So, tehokas literally means "having a lot of power" or "efficient".
