Questions & Answers about Torilla on paljon väkeä.
Why do we use väkeä here instead of ihmisiä for 'people'?
Väki is a collective noun meaning a crowd, folk, or people. While you could perfectly well say Torilla on paljon ihmisiä, using väkeä emphasizes a gathered mass or crowd rather than a collection of individuals. Because it follows paljon (a lot), it must be in the partitive singular case: väkeä.
Given our current lesson on the -kko / -kkö group suffix, why doesn't this sentence use one to describe the crowd?
Because väki is inherently a collective noun, it doesn't need a suffix to denote a group. The -kko / -kkö suffix is instead used to derive new collective nouns from basic words, such as turning kaksi (two) into kaksikko (a duo), or koivu (birch) into koivikko (a birch grove).
Why is the verb on in the singular when the English translation says 'are'?
This is a classic existential sentence (Location + verb + subject). In Finnish existential sentences, the verb is always in the third-person singular (on). Additionally, väki is grammatically a singular mass noun. Even though it conceptually represents multiple people, the word itself takes singular agreement.
Why do we use the adessive case -lla in torilla instead of the inessive -ssa?
