Savityöpaja on auki kymmeneltä.

Because Finnish usually writes compound nouns as a single word.

• savi = clay
• työpaja = workshop, studio, workshop space

So savityöpaja is literally clay workshop / clay studio. This is very normal in Finnish. English often uses two words where Finnish uses one:

• kirjakauppa = bookshop
• kahvikuppi = coffee cup
• savityöpaja = clay workshop

On is the third-person singular form of the verb olla, which means to be.

So:

• savityöpaja on = the clay workshop is

It is on because savityöpaja is singular. If the subject were plural, Finnish would use ovat:

• Savityöpajat ovat auki kymmeneltä. = The clay workshops are open at ten.

Finnish often uses olla + auki to describe the state of being open.

So on auki means is open. It describes a condition, not the action of opening.

Compare:

• on auki = is open
• aukeaa = opens
• avataan = is opened / people open it

This is similar to on kiinni = is closed.

Most literally, it means is open at ten.

That matters because on auki describes a state. It tells you that at ten o’clock, the place is open. It does not strictly say that ten is the opening moment.

If you specifically want opens at ten, Finnish more clearly says:

• Savityöpaja aukeaa kymmeneltä.

In everyday context, though, English might sometimes translate on auki kymmeneltä more loosely depending on what information is being asked for.

Because Finnish uses a special case form for exact clock times.

• kymmenen = ten
• kymmeneltä = at ten o’clock

This is the normal pattern with clock times:

• yhdeltä = at one
• kahdelta = at two
• kolmelta = at three
• kymmeneltä = at ten

So after a sentence like this, Finnish does not use the plain number kymmenen.

It is the ablative form, with the ending -lta/-ltä.

In many other situations, the ablative often has meanings like from or off of, but with clock times Finnish uses this case idiomatically to mean at a certain time.

So learners usually just memorize this as the normal clock-time pattern:

• Monelta? = At what time?
• Kymmeneltä. = At ten.

A very natural question is:

• Monelta savityöpaja on auki?

That means At what time is the clay workshop open?

Notice that the question word is monelta, which matches the same time pattern as kymmeneltä. This is very common in Finnish: the question word often appears in the same case as the answer.

Yes. You can say:

• Savityöpaja on auki kello kymmeneltä.

Here kello means at the time of / o’clock. In many situations, it is optional.

So both of these are fine:

• Savityöpaja on auki kymmeneltä.
• Savityöpaja on auki kello kymmeneltä.

Without kello is very natural when it is already clear that you are talking about time.

Finnish has no articles like English a/an/the.

So savityöpaja can mean:

• a clay workshop
• the clay workshop

The exact English choice depends on context, not on a separate word in Finnish.

That is why a simple Finnish noun often has to be translated differently in different situations.

No, Finnish word order is fairly flexible, but the version here is a natural neutral one:

• Savityöpaja on auki kymmeneltä.

This puts the subject first, then the verb phrase, then the time.

You can move things around for emphasis. For example:

• Kymmeneltä savityöpaja on auki.

This emphasizes at ten more strongly.

So the meaning stays similar, but the focus changes. The original sentence is a good basic default order.
