Il labirinto è dietro gli autoscontri.

Italian usually uses the definite article more often than English. So il labirinto means the maze.

• il = the for a masculine singular noun
• labirinto = maze

You could say just labirinto in some special contexts, but in a normal sentence like this, il labirinto is the natural form.

È is the third-person singular of essere (to be), so here it means is.

The accent matters because:

• è = is
• e = and

So Il labirinto è dietro gli autoscontri means The maze is behind the bumper cars, not The maze and behind the bumper cars.

Dietro means behind.

In many cases, dietro can be used directly before a noun:

• dietro gli autoscontri = behind the bumper cars

You may also see dietro a, especially before pronouns or in other contexts:

• dietro a me = behind me
• dietro al teatro = behind the theater

Both patterns exist, but in this sentence dietro gli autoscontri is completely natural.

Because autoscontri is a masculine plural noun beginning with a vowel sound (a), Italian uses gli, not i.

A quick guide for masculine plural definite articles:

• i before most consonants: i libri
• gli before vowels and certain consonant groups: gli amici, gli studenti, gli autoscontri

So:

• singular: l'autoscontro or lo scontro depending on the noun
• plural: gli autoscontri

Autoscontri are the fairground/amusement-park cars you drive into each other for fun: bumper cars.

The singular is usually autoscontro.

So:

• un autoscontro = a bumper car
• gli autoscontri = the bumper cars

Italian often refers to this attraction by the plural noun autoscontri, meaning literally bumper cars.

English can say:

• the bumper cars
• the bumper car ride

Italian commonly uses the plural attraction name itself:

• gli autoscontri

So the Italian is perfectly natural even if English might sometimes choose a singular expression like the bumper car ride.

Labirinto is masculine, which is why it takes il:

• il labirinto

Many Italian nouns ending in -o are masculine, though there are exceptions. Its plural would be:

• il labirinto = the maze
• i labirinti = the mazes

Yes, very close.

• Il labirinto = the maze
• è = is
• dietro gli autoscontri = behind the bumper cars

So the structure is:

subject + verb + location

This is one reason the sentence feels quite straightforward for an English speaker.

Gli can be tricky for English speakers. Here it is pronounced roughly like lyee, though that is only an approximation.

A few tips:

• The gl sound in gli is not a normal English gl.
• It is similar to the lli sound in some pronunciations of Spanish calle, or the lli sound in million for some English speakers, but not exactly the same.
• Because it comes before a in autoscontri, the phrase flows together smoothly: gli autoscontri.

If you are a beginner, an approximate lyee autoscontri is a reasonable starting point.

Yes. That would also be natural and means something like:

The maze is located behind the bumper cars.

Compare:

• Il labirinto è dietro gli autoscontri. = simple, direct, everyday
• Il labirinto si trova dietro gli autoscontri. = slightly more explicit about location

Both are correct. The version with è is shorter and very common.

Yes. In natural English, behind the bumper cars and in back of the bumper cars can express the same idea. Italian dietro covers that basic spatial meaning.

So if you understand the sentence as describing location to help someone find the maze, that is exactly how dietro is being used here.
