Tervetuloa kurssille!

Not in the way a beginner might expect. It is not the normal imperative come! In modern Finnish, tervetuloa is best learned as a fixed expression meaning welcome.

It is historically connected with the idea of coming/arrival, which is why it may look related to tulla, but for practical learning it is much better to memorize tervetuloa as one whole expression.

They are used differently:

• Tervetuloa! = the greeting Welcome!
• tervetullut = an adjective meaning welcome

For example:

• Tervetuloa kurssille! = a greeting
• Olet tervetullut kurssille. = You are welcome to the course.

So you would not normally greet someone by saying tervetullut! by itself. The usual welcoming expression is tervetuloa!

Because -lle is the allative case, which often means to, onto, or toward.

So:

• kurssi = course
• kurssille = to the course

With events, classes, and similar destinations, Finnish often uses -lle where English uses to. That is why Tervetuloa kurssille! is the natural form.

Normally, no. In this context, kurssille is the idiomatic choice.

• kurssille = to the course
• kurssiin would more literally mean into the course

That sounds wrong or at least unnatural when welcoming someone to a class or course. Finnish usually treats this kind of destination as something you go to, not into.

Finnish has no articles, so there is no separate word for a, an, or the.

That means kurssille can mean either to a course or to the course, depending on context. In this sentence, the context makes it clear that the meaning is to the course.

It can be either. The form tervetuloa works when speaking to:

• one person
• several people

So this sentence can mean:

• Welcome to the course! said to one person
• Welcome to the course! said to a group

If you want to make the group meaning clearer, you can add another word, for example kaikki (everyone).

Yes. Tervetuloa! by itself is very common and completely natural.

Adding kurssille simply tells the listener what they are being welcomed to. So:

• Tervetuloa! = Welcome!
• Tervetuloa kurssille! = Welcome to the course!

A simple learner-friendly guide is:

TER-ve-tu-lo-a KURS-sil-le

A few helpful points:

• Stress is on the first syllable of each word.
• tuloa has three syllables: tu-lo-a
• Double consonants matter in Finnish, so ss and ll are pronounced a little longer than single consonants.

So try to avoid saying kur-si-le. The longer consonants are part of correct pronunciation: kurs-sil-le.
