Il video mostra il furto.

Because Italian uses the definite article il for both nouns here:

• il video = the video
• il furto = the theft

This is very normal in Italian. English sometimes uses the less often than Italian, but in this sentence both languages use it in the same way.

Mostra is the third person singular form of the verb mostrare (to show).

The subject is il video, which is singular, so the verb must also be singular:

• io mostro = I show
• tu mostri = you show
• lui/lei mostra = he/she shows
• il video mostra = the video shows

So mostra matches il video.

The base form, or infinitive, is mostrare, meaning to show.

In this sentence:

• mostrare → infinitive
• mostra → shows

This is a regular -are verb.

Yes, Italian can sometimes change word order, but this sentence uses the most basic and natural order:

• Subject: Il video
• Verb: mostra
• Object: il furto

So it follows the standard pattern:

subject + verb + object

That makes it a very straightforward sentence.

Furto is a noun. It means theft or robbery/the stealing, depending on context, though theft is the most direct match.

In this sentence, it is the direct object of mostra:

• What does the video show?
• Il furto

Because the sentence is talking about the event itself as a thing that is shown.

• furto = the theft (noun)
• rubare = to steal (verb)

So:

• Il video mostra il furto = The video shows the theft.

If you used rubare, you would need a different structure, because rubare is an action, not a noun.

Yes. In standard Italian, video is masculine, so it takes il:

• il video
• i video (plural)

Notice that the plural usually stays the same in form: video can be singular or plural, depending on the article.

Because video is one of those nouns that usually remains unchanged in Italian.

So you get:

• il video = the video
• i video = the videos

The article changes, but the noun usually does not.

A simple pronunciation guide is:

eel VEE-deh-oh MOH-strah eel FOOR-toh

A few helpful notes:

• il sounds like eel
• video has three clear syllables: vi-de-o
• mostra has an open, clear o
• furto has the rolled or tapped Italian r

Very often, yes. Mostrare is commonly used much like English to show:

• mostrare un video = to show a video
• mostrare una foto = to show a photo
• mostrare un documento = to show a document

In this sentence, though, the subject is the video itself:

• Il video mostra il furto = The video shows the theft

So the video is what reveals or displays what happened.

Yes, that is also possible.

• Il video mostra il furto
• Il video fa vedere il furto

Both can mean The video shows the theft.

However, mostrare is often a bit more direct and concise, and it fits very naturally in this sentence.

Yes, usually it does. The article il suggests a specific theft, not theft in general.

So il furto means:

• the theft
• a particular theft that the speaker and listener can identify from context

If you wanted to speak more generally, the structure might be different.

They are related, but they are not exactly the same.

• furto = theft, stealing something
• rapina = robbery, usually involving force or threat

So if no violence or threat is implied, furto is often the better word. That is why il furto is an important vocabulary item to learn separately from la rapina.
