Learn Hardcore Finnish: Kartan toisessa kulmassa näkyy pieni kahvila, jossa nautin usein teetä. - In the other corner of the map you can see a small café where I often enjoy tea.

Kartan is the genitive of kartta, showing possession: literally “the map’s ….”
Toisessa is the inessive singular of toinen (“second/other”) and kulmassa is the inessive singular of kulma (“corner”). The inessive case (ending -ssa/-ssä) expresses “in” or “inside,” so toisessa kulmassa means “in the other corner.”

What does näkyy mean here and why is it used instead of on?

Näkyy is the third person singular form of näkyä, meaning “to be visible” or “to appear.” On a map you often say something “is visible” (näkyy) rather than simply “is” (on). It highlights that the café appears on the map, not just that it exists.

Why is pieni kahvila in the nominative case and why doesn’t pieni carry any extra ending?

Pieni kahvila is the subject of näkyy, so both words are in the nominative singular. The adjective pieni agrees with kahvila in case, number, and form, so it stays in the plain nominative singular.

What role does jossa play, and why can’t we use missä or an uninflected joka here?

Jossa is the inessive singular of the relative pronoun joka, meaning “in which.” It introduces the relative clause referring back to kahvila (“the café in which I often enjoy tea”). You can’t use missä (interrogative/locative pronoun) or uninflected joka in a relative clause; you must use the correct case form of joka.

Why is the subject “I” dropped before nautin, and how do we know who is performing the action?

Finnish typically omits personal pronouns because the verb ending carries that information. Nautin ends in -n, which marks first person singular (“I enjoy”). Adding minä would be redundant unless you want extra emphasis.

Why is teetä in the partitive case rather than the nominative tee?

After verbs of consumption or enjoyment (like nauttia), Finnish uses the partitive (ending -tä/-ttä) to express an undefined amount or ongoing action. Teetä means “(some) tea,” whereas tee as nominative would imply “the tea” as a complete, countable entity.

How does the adverb usein fit into the sentence, and could it be placed elsewhere?

Usein (“often”) is an adverb of frequency. Finnish word order is flexible, so you could say nautin usein teetä, usein nautin teetä, or nautin teetä usein. Placing usein immediately after the verb is common and keeps the focus on how frequently the action occurs.
