Keraamikko pyörittää dreijaa.

Keraamikko is in the nominative singular, which is the basic dictionary form. In this sentence, it is the subject: the person doing the action.

So structurally:

• keraamikko = subject
• pyörittää = verb
• dreijaa = object

This is a very useful contrast in Finnish:

• pyöriä = to spin, rotate, go round
• pyörittää = to spin something, rotate something, make something turn

So pyöriä is intransitive: the thing itself is turning.
For example, a wheel spins.

Pyörittää is transitive: someone causes something else to turn.
That is why it fits here: the potter is making the wheel turn.

This kind of pair is common in Finnish: one verb describes something happening by itself, and another describes causing it to happen.

Here pyörittää is present tense, third person singular.

The subject is keraamikko, which is singular, so the verb is in the matching singular form.

A few forms of the verb are:

• minä pyöritän = I spin / I am spinning
• sinä pyörität = you spin / are spinning
• hän pyörittää = he/she spins / is spinning

So in this sentence, keraamikko pyörittää means the potter spins / is spinning.

Because dreijaa is in the partitive singular.

The basic form is:

• dreija = nominative singular

The partitive singular is:

• dreijaa

In Finnish, objects often appear in either a total object form or a partitive form. Here the partitive is natural because the action is seen as ongoing, unbounded, or simply as an activity rather than a completed result.

So pyörittää dreijaa feels like:

• spinning the wheel
• operating the wheel
• turning the wheel as an ongoing action

This is very common in Finnish with actions that do not have a clear endpoint.

In this sentence, dreijaa is the natural choice.

Using the partitive suggests an ongoing activity: the potter is working the wheel, turning it, using it. That matches the situation very well.

A total object form such as dreijan would suggest a more bounded or completed action, which does not fit as naturally with this kind of continuous activity. So for a learner, it is best to think of pyörittää dreijaa as the normal pattern here.

It can mean either, depending on context.

Finnish present tense often covers both:

• simple present: spins
• present continuous: is spinning

So Keraamikko pyörittää dreijaa could mean:

• The potter spins the wheel
• The potter is spinning the wheel

If the wider context is describing what is happening right now, English often uses is spinning. If it is describing a general action or habit, English may use spins.

The basic neutral word order here is subject – verb – object:

• Keraamikko pyörittää dreijaa.

That is the most straightforward version.

But Finnish word order is more flexible than English, and different orders can change the emphasis. For example, moving dreijaa to the front could put extra focus on the wheel. Even so, the original sentence is the most neutral and beginner-friendly order.

A few key pronunciation points:

• Finnish stress is usually on the first syllable
• double vowels are pronounced long
• double consonants are also pronounced longer or more strongly

So:

• pyörittää has a long tt and a long final ää
• dreijaa has a long final aa

Also:

• y is not like English y in yes; it is a vowel
• ö is also a vowel that English does not have exactly

Very roughly:

• pyörittää ≈ PYÖ-rit-taa
• dreijaa ≈ DREI-jaa

The exact sounds take practice, but the most important beginner point is to notice that the doubled letters really matter in Finnish.

Yes. Dreija is the normal word for a potter’s wheel.

It is a concrete noun, and in this sentence it behaves exactly as you would expect a noun to behave:

• basic form: dreija
• partitive singular: dreijaa

So although it may look unfamiliar, grammatically it is a regular noun in this sentence.
