La mobilità permette la rotazione.

Because both nouns are feminine singular, so they take the definite article la.

• la mobilità = the mobility
• la rotazione = the rotation

Italian often uses the definite article more regularly than English, especially with general or abstract nouns. So even if English might say Mobility allows rotation, Italian naturally says La mobilità permette la rotazione.

You usually learn the gender together with the noun: la mobilità.

A helpful pattern is that many Italian nouns ending in -tà are feminine, such as:

• la città = the city
• la necessità = necessity
• la libertà = freedom

So la mobilità follows a very common pattern.

The accent shows that the stress falls on the last syllable: mo-bi-li-tà.

This is important in Italian spelling. Words stressed on the final syllable usually show a written accent. So:

• mobilità
• città
• università

The accent is part of the correct spelling, not optional.

Permette is the third person singular present tense of permettere.

So:

• io permetto = I allow
• tu permetti = you allow
• lui/lei permette = he/she allows

In this sentence, the subject is la mobilità, which is singular, so the verb must also be singular:

• La mobilità permette... = Mobility allows...

Because permettere can take a direct object.

Here, la rotazione is the thing being allowed, so it comes directly after the verb:

• permettere qualcosa = to allow something

So:

• La mobilità permette la rotazione.

No extra preposition is needed.

However, when another verb follows, Italian often uses di:

• permettere di fare qualcosa = to allow doing something / to allow someone to do something

Example:

• Questo permette di ruotare l'oggetto. = This allows the object to rotate / allows one to rotate the object.

No, this is the normal Italian word order: subject + verb + object.

• La mobilità = subject
• permette = verb
• la rotazione = object

So the structure is very similar to English:

• Mobility allows rotation.

Italian can change word order for emphasis, but this sentence is neutral and standard.

Normally, no. That would sound unnatural in standard Italian.

With abstract nouns like these, Italian usually wants the articles:

• La mobilità permette la rotazione.

Leaving them out may sound incomplete or overly technical in most contexts. In headings, labels, or very specialized writing, articles are sometimes omitted, but in an ordinary sentence they should stay.

Yes. Rotazione is a feminine singular noun:

• la rotazione

Many Italian nouns ending in -zione are feminine:

• la situazione
• la lezione
• la direzione
• la rotazione

So this is another useful pattern to remember.

Yes. Permettere can often be translated as allow, permit, or sometimes make possible, depending on context.

So this sentence could be understood as:

• Mobility allows rotation
• Mobility permits rotation
• Mobility makes rotation possible

The exact English choice depends on style and context, but the Italian is straightforward.

A simple pronunciation guide is:

la mo-bee-lee-TA per-MET-te la ro-ta-TSYO-ne

A few notes:

• mobilità is stressed on the last syllable: -tà
• permette is stressed on met
• rotazione is stressed on ne, pronounced roughly ro-ta-TSYO-ne

If you say it smoothly:

La mobilità permette la rotazione.

Usually it refers to the concepts in general.

In Italian, the definite article is often used with general ideas, abstract nouns, and categories. So:

• La mobilità permette la rotazione.

can mean something like:

• Mobility allows rotation
• The presence of mobility allows rotation

It does not necessarily mean one specific, previously mentioned mobility. Context decides that.
