Prima che arrivi Natale, Laura vuole comprare delle luci nuove e una sciarpa per sua madre.

Because prima che is normally followed by the subjunctive in Italian when it introduces an action that has not happened yet.

So:

• prima che arrivi Natale = before Christmas arrives / before Christmas comes
• arrivi is the present subjunctive of arrivare

This is very common:

• Ti chiamo prima che tu parta. = I’ll call you before you leave.
• Andiamo via prima che piova. = Let’s leave before it rains.

Even though English does not usually show this difference, Italian does.

Prima che means before when it is followed by a verb clause.

In this sentence, it introduces a whole action:

• arrivi Natale = Christmas arrives / comes

So:

• Prima che arrivi Natale = Before Christmas comes

Compare:

• prima di Natale = before Christmas
• prima che arrivi Natale = before Christmas arrives

Both are possible, but prima che arrivi Natale is a fuller verbal structure.

Yes. Prima di Natale is very natural and probably more common in everyday speech for this meaning.

So these are both possible:

• Prima di Natale, Laura vuole comprare...
• Prima che arrivi Natale, Laura vuole comprare...

The difference is:

• prima di Natale = more compact, using a noun phrase
• prima che arrivi Natale = more explicit, using a clause with a verb

Neither is wrong here.

In Italian, holidays such as Natale usually appear without an article when speaking generally.

So:

• a Natale = at Christmas
• prima di Natale = before Christmas
• arriva Natale = Christmas is coming

This is similar to how English often says Christmas without the.

Because volere is a modal-like verb meaning to want, and it is followed by an infinitive.

So:

• vuole = she wants
• comprare = to buy

Together:

• vuole comprare = she wants to buy

This is the normal pattern in Italian:

• voglio mangiare = I want to eat
• vuoi uscire? = do you want to go out?
• Laura vuole comprare = Laura wants to buy

Here delle means something like some.

So:

• delle luci nuove = some new lights

This is called a partitive article. It often expresses an indefinite plural idea, where English may use some or no word at all.

Compare:

• compro delle mele = I’m buying some apples
• ho visto degli amici = I saw some friends
• vuole comprare delle luci nuove = she wants to buy some new lights

In English, some is often optional, but in Italian this structure is very common.

Luci is the plural of luce, and in this context it usually means lights, especially decorative or Christmas lights.

So delle luci nuove most naturally suggests:

• some new lights
• likely decorative lights or string lights

Italian often uses luci in this broad way, just like English lights.

In Italian, adjectives often come after the noun.

So:

• luci nuove = new lights
• sciarpa rossa = red scarf
• casa grande = big house

Some adjectives can come before the noun, but with many descriptive adjectives, especially color, size, type, or condition, the position after the noun is very common and neutral.

So delle luci nuove is the standard order.

Because with family members in the singular, Italian usually does not use the article before a possessive.

So:

• sua madre = her mother
• suo padre = her father
• mia sorella = my sister

This is a very important pattern:

• mia madre, not usually la mia madre
• tuo fratello, not usually il tuo fratello

But there are some exceptions. The article is usually used:

• with plural family members: i miei genitori
• with some modified forms: la mia sorellina
• in certain emphatic or regional uses

Here, sua madre is exactly what you would expect.

Here per means for.

So:

• una sciarpa per sua madre = a scarf for her mother

It shows the intended recipient of the scarf.

Compare:

• un regalo per te = a gift for you
• una lettera per Marco = a letter for Marco
• un cappotto per mia sorella = a coat for my sister

By itself, sua madre can mean:

• his mother
• her mother
• sometimes even your formal mother depending on context

Italian suo/sua agrees with the thing possessed, not with the owner:

• madre is feminine singular
• so the possessive is sua

To know whose mother it is, you use context. In this sentence, since the subject is Laura, sua madre is understood as her mother.

Because Prima che arrivi Natale is an introductory clause placed before the main clause.

So the sentence structure is:

• Prima che arrivi Natale = introductory time clause
• Laura vuole comprare... = main clause

In English and Italian, a comma is commonly used after this kind of opening clause. It helps readability.

If the order were reversed, the comma would often disappear:

• Laura vuole comprare delle luci nuove e una sciarpa per sua madre prima che arrivi Natale.

Yes. E means and, and it links the two direct objects of comprare:

• delle luci nuove
• una sciarpa per sua madre

So Laura wants to buy:

1. some new lights
2. a scarf for her mother

The verb comprare applies to both.

Yes. Italian commonly uses arrivare with times, seasons, holidays, and events in a way that sounds completely natural.

Examples:

• Arriva l’estate. = Summer is coming.
• Quando arriva il weekend... = When the weekend comes...
• È arrivato Natale. = Christmas has arrived / It’s Christmas.

So arrivi Natale is a very natural Italian way to talk about Christmas approaching.

It is the present subjunctive.

For arrivare, the present subjunctive forms are:

• che io arrivi
• che tu arrivi
• che lui/lei arrivi
• che noi arriviamo
• che voi arriviate
• che loro arrivino

In this sentence, the subject is Natale, which is treated as third person singular, so:

• che arrivi Natale

Italian often omits subject pronouns like lei, but it can still use a noun subject when needed.

Here Laura is not a pronoun; it identifies clearly who wants to buy the items.

So:

• Laura vuole comprare... = Laura wants to buy...
• Vuole comprare... = She wants to buy...

Both are possible, but using Laura makes the sentence clear and complete, especially if it starts a story or example.
