La torneta gira despacio.

Because torneta is feminine singular in this sentence, so it takes the feminine singular article la.

In Spanish, nouns have grammatical gender, and the article has to match:

• la = feminine singular
• el = masculine singular

So la torneta is the correct form here.

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

That means it matches subjects like:

• él
• ella
• usted
• any singular noun, such as la torneta

So La torneta gira means the subject la torneta performs the action of turning/spinning.

Spanish usually does not need a subject pronoun when the verb ending already shows who or what the subject is.

Here, gira already tells you it is third-person singular, and the noun la torneta is explicitly there anyway, so adding ella would be unnecessary.

Spanish often prefers:

• La torneta gira despacio

rather than:

• Ella gira despacio

unless you want special emphasis or contrast.

Because despacio is an adverb, and it modifies the verb gira. It tells us how the turning happens.

• gira despacio = turns slowly

But lenta is an adjective, so it describes the noun itself:

• La torneta es lenta = the turntable/device is slow

So in this sentence, despacio is the natural choice because it describes the action, not the object.

Yes. Lentamente is also correct.

• La torneta gira despacio
• La torneta gira lentamente

Both are grammatical. The difference is mainly style:

• despacio is very common and natural in everyday speech
• lentamente can sound a bit more formal or more explicitly descriptive

Because that is the most normal word order in Spanish for this kind of sentence.

A neutral sentence is:

• Subject + verb + adverb
• La torneta gira despacio

Spanish word order is flexible, but this version sounds the most standard and natural. Putting despacio somewhere else is possible in some contexts, but it usually adds emphasis or sounds more literary.

Yes. That version is also correct, but it is slightly different in focus.

• La torneta gira despacio: simple present; can describe what it does generally or what it is doing, depending on context
• La torneta está girando despacio: emphasizes that it is happening right now

Spanish often uses the simple present where English might use the present continuous, so gira is perfectly natural.

Because girar can work perfectly well here without se.

In this sentence, la torneta is simply rotating, so gira is enough.

Adding se can change the nuance and often suggests something more like:

• turning around
• changing orientation
• a different kind of movement depending on context

So for simple rotation, gira is the straightforward form.

In Spain, gira is pronounced with the Spanish g sound used before i, which is not like the English g in go.

A few key points:

• gi sounds like the Spanish j sound
• it is a throaty sound, similar to the ch in Scottish loch for many learners
• the stress is on the first syllable: GI-ra

So the important thing is: do not pronounce it like gee-ra with a hard English g.

In standard peninsular Spanish, despacio is stressed on pa:

• des-PA-cio

Also, in most of Spain, the ci is pronounced with a th sound like in think:

• roughly des-PA-thyo

That is a Spain-specific pronunciation feature. In much of Latin America, the same word would sound more like des-PA-syo.

Yes, Spanish allows some flexibility, but the meaning or tone can shift.

The most neutral version is:

• La torneta gira despacio

You might also see:

• Despacio gira la torneta

That is possible, but it sounds more marked, poetic, or emphatic. For everyday Spanish, the original order is the best one to learn first.
