La bambina abbraccia la sua bambola.

Because there are two separate noun phrases:

• la bambina = the subject
• la sua bambola = the object

In Italian, la is the feminine singular definite article, so it is used with both bambina and bambola, since both nouns are feminine singular.

Also, Italian usually keeps the article before a possessive adjective, so la sua bambola is normal Italian, even though English would just say her doll without the.

They are all feminine singular forms.

• bambina is a feminine singular noun
• bambola is also a feminine singular noun
• sua is the feminine singular form of the possessive adjective

Italian words often change form to match gender and number. Here everything matches the noun bambola where needed, and both nouns happen to be feminine singular.

Because the possessive adjective agrees with the thing being possessed, not with the owner.

Here, the possessed thing is bambola, which is feminine singular, so the correct form is sua.

Compare:

• il suo libro = his/her book
• la sua bambola = his/her doll

Even if the owner is a girl, a boy, or someone else, the form depends on libro or bambola, not on the owner.

Not by itself. Sua can mean:

• his
• her
• its
• sometimes your in the formal sense

Italian possessives are often less specific than English. You usually understand the meaning from context.

In this sentence, because the subject is la bambina, the natural interpretation is her, but the word sua alone does not force that meaning.

Because Italian normally uses the definite article with possessive adjectives.

So you usually get:

• il mio libro
• la tua casa
• la sua bambola

This is different from English.

A common exception is with singular close family members, where the article is often dropped:

• mia madre
• tuo fratello
• sua sorella

But bambola is not a family member, so la sua bambola is the standard form.

Abbraccia is the third-person singular present indicative of the verb abbracciare.

So:

• io abbraccio = I hug
• tu abbracci = you hug
• lui/lei abbraccia = he/she hugs

Since the subject is la bambina, the verb has to be abbraccia.

It is pronounced roughly ab-BRAHT-cha.

A few useful details:

• bb is a double consonant, so it is held a little longer than a single b
• ccia sounds like cha
• the stress falls on bra

A rough pronunciation guide is ab-BRAT-cha.

No. It is the basic Italian word order:

subject + verb + object

• La bambina = subject
• abbraccia = verb
• la sua bambola = object

This is very similar to normal English word order.

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

Yes, grammatically it could.

Italian often drops subject pronouns and sometimes even noun subjects when the context is clear. So Abbraccia la sua bambola could mean:

• She hugs her doll
• He hugs his/her doll
• sometimes even You hug your doll in formal speech

Because abbraccia only tells you it is third-person singular or formal you, the full subject La bambina makes the sentence clearer.

Usually that is how it will be understood, yes, especially because of the context.

But strictly speaking, la sua bambola can sometimes be ambiguous in Italian, just like his/her doll can be ambiguous in English.

If Italian wants to be extra clear that it is the subject’s own doll, it can sometimes use propria:

• La bambina abbraccia la propria bambola

That sounds a bit more explicit or formal. In normal everyday language, la sua bambola is usually enough.

They do look similar, but they are different words:

• bambina = girl
• bambola = doll

They are related in sound but not interchangeable. For an English speaker, it is easy to mix them up at first, so it helps to remember:

• bambina refers to a child
• bambola refers to a toy

Because Italian usually does not need one when the subject is already expressed or clear.

Here, la bambina already tells you who is doing the action, so adding lei would normally be unnecessary.

Italian often avoids repeating subject pronouns unless there is emphasis, contrast, or possible confusion.
