Questions & Answers about Minä opiskelen suomea sunnuntaisin.

Why is the object suomea in the partitive case?

Because the verb opiskella requires its direct object in the partitive case when referring to an ongoing or incomplete action. The partitive singular of suomi is suomea, so opiskelen suomea literally means “I study Finnish” without implying you’ve finished it.

What is sunnuntaisin, and how is it formed?

Sunnuntaisin is an adverbial form meaning “on Sundays” (habitually). It comes from sunnuntai (Sunday) by taking the stem sunnunta- and adding the instructive plural ending -sin, which conveys a repeated or habitual action.

What’s the difference between sunnuntaina and sunnuntaisin?

• sunnuntaina (adessive singular) means “on (a specific) Sunday.”
• sunnuntaisin (instructive plural) means “on Sundays” in general, indicating repetition.
Use sunnuntaina for one particular Sunday, sunnuntaisin for a weekly habit.

Can I omit Minä and just say Opiskelen suomea sunnuntaisin?

Yes. Finnish is a pro-drop language, so the subject pronoun minä is optional when the verb ending (-len) already shows 1st person singular. Including minä adds emphasis or clarity but isn’t required.

Why is suomea written in lowercase?

In Finnish, names of languages are common nouns, not proper nouns, so they aren’t capitalized. Hence suomi and its partitive suomea stay lowercase.

Could I say Minä opiskelen suomen kieltä sunnuntaisin instead?

Yes. suomen kieltä (“the Finnish language” in partitive) is more explicit. It’s grammatically correct, though Finns often shorten it to suomea in everyday speech.

Where else can I place the time expression sunnuntaisin in the sentence?

Finnish word order is flexible. You can move sunnuntaisin for emphasis:
• Sunnuntaisin opiskelen suomea. (Emphasizes “on Sundays”)
• Minä sunnuntaisin opiskelen suomea. (Less common)
The most neutral position is at the end.

What does the verb form opiskelen tell me?

• The infinitive is opiskella (“to study”).
• opiskelen is present tense, 1st person singular: “I study” or “I am studying.”
• Finnish present tense covers both habitual and continuous aspects, so it works for “I study Finnish regularly” or “I am studying Finnish right now.”
