Questions & Answers about Kuuluisa keksijä patentoi hehkulampun vuonna 1880.
Why is the year 1880 read in the nominative (basic) case here? Shouldn't numbers be inflected in Finnish?
Usually, yes! But when you use the word vuonna (in the year), the number that follows is read strictly in the uninflected nominative case. So you read this as vuonna tuhat kahdeksansataa kahdeksankymmentä. If you dropped the word vuonna, you would have to inflect every single part of the number into the essive case, which is incredibly cumbersome. Using vuonna followed by the nominative is the standard, everyday way to express calendar years.
Why do we use the essive case vuonna instead of saying 'in the year' with the inessive case like vuodessa?
In Finnish, the essive case (ending in -na or -nä) is used to express when an event happens for days of the week and specific years. While you use the inessive case for months (like tammikuussa for 'in January'), for years you must use vuonna (the essive form of the noun vuosi).
How do we know patentoi is in the past tense here? Doesn't the present tense look exactly the same?
You are exactly right! For verbs ending in -oida (like patentoida), the third-person singular form is patentoi in both the present and past tense. At this level, you have to rely entirely on context. Since the sentence explicitly states the action happened in 1880, we know it translates as 'patented' rather than 'patents'.
Why is the object hehkulampun in the genitive-like accusative case instead of the partitive?
