Il tornio da vasaio gira lentamente.

Il is the masculine singular definite article, meaning the.

It is used because tornio is a masculine singular noun:

• il tornio = the wheel / the lathe

Italian uses articles very regularly, often more than English does.

The main noun is tornio.

The part da vasaio describes what kind of tornio it is. So the structure is:

• tornio = wheel / lathe
• da vasaio = for a potter / used by a potter

Together, tornio da vasaio means potter’s wheel.

Because da here shows purpose or type, not ownership.

So:

• tornio da vasaio = a wheel used by a potter, a potter’s wheel
• tornio del vasaio = the potter’s wheel in the sense of the wheel belonging to the potter

This noun + da + noun pattern is very common in Italian:

• spazzolino da denti = toothbrush
• sala da pranzo = dining room
• scarpe da tennis = tennis shoes

Gira is the third-person singular present indicative of girare.

So:

• io giro = I turn / I spin
• tu giri = you turn
• lui/lei gira = he/she/it turns

Since il tornio da vasaio is singular, the verb is singular too:

• Il tornio da vasaio gira = The potter’s wheel turns / spins

It can mean either, depending on context.

With something like a wheel, English might say:

• turns
• spins
• rotates

So gira is a very natural verb here.

Lentamente is an adverb meaning slowly.

It comes from the adjective lento / lenta = slow, plus -mente, which often works like English -ly:

• lento = slow
• lentamente = slowly

This is a very common pattern in Italian:

• rapido → rapidamente
• facile → facilmente

That is the most neutral and common placement here.

So:

• gira lentamente = turns slowly

Italian adverbs are often placed after the verb, especially in simple sentences like this one. Other positions are sometimes possible for emphasis, but this version is the most natural for a learner to use.

Yes, but the original order is the most standard:

• Il tornio da vasaio gira lentamente.

You may also see different orders for emphasis, style, or rhythm, but they are less neutral. For everyday use, stick with:

• subject + verb + adverb

A rough English-style guide:

• tornio ≈ TOR-nyo
• vasaio ≈ va-ZA-yo

So the whole sentence is roughly:

eel TOR-nyo da va-ZA-yo JEE-ra len-ta-MEN-te

The stress is on:

• TOR in tornio
• ZA in vasaio
• MEN in lentamente

No. You may also see ceramista.

The difference is roughly:

• vasaio = potter, especially in the traditional sense
• ceramista = ceramic artist / ceramics maker

In this sentence, vasaio fits very naturally because tornio da vasaio is a normal way to say potter’s wheel.
