Questions & Answers about Kaupunki, joka kasvaa nopeasti, tarvitsee kehitystä.
Where does the word kehitys come from, and how does the -ys suffix work here?
Kehitys (development) is derived from the verb kehittyä (to develop or evolve). By adding the -ys suffix to the verb stem, you create a noun that describes the action, process, or result of that verb. Because of vowel harmony with the front vowels in the stem, it takes -ys instead of -us.
Why is kehitystä in the partitive case here?
The verb tarvita (to need) requires an object. Because development is an abstract, uncountable concept in this context, the object must be in the partitive case (kehitystä). If the city needed a specific, countable thing like a new school, it would use the accusative case.
Could I use mikä instead of joka to say 'which' in this sentence?
No, you must use joka. In Finnish, joka is used when referring back to a specific preceding noun (in this case, kaupunki). The other relative pronoun, mikä, is mainly used when referring to a whole preceding clause, a superlative, or a pronoun like kaikki.
How is the adverb nopeasti (fast) formed?
It is formed by taking the adjective nopea (quick) and adding the suffix -sti. This is the standard way to turn an adjective into an adverb in Finnish, functioning just like the '-ly' ending in English (quickly).
