Στον τεχνικό έλεγχο επιθεωρούνται το αμάξωμα και ο κινητήρας.

Στον is the contracted form of σε + τον.

• σε = in / at / to
• τον = the (masculine accusative singular)

So στον τεχνικό έλεγχο literally means something like in the technical inspection or during the technical inspection.

In this sentence, it sets the context: during the inspection.

Because after σε (here contracted in στον), Greek normally uses the accusative case.

The dictionary form is:

• ο τεχνικός έλεγχος = the technical inspection

But after σε, it becomes:

• στον τεχνικό έλεγχο

So both the adjective and the noun change form to match the masculine accusative singular:

• τεχνικός → τεχνικό
• έλεγχος → έλεγχο

In this context, τεχνικός έλεγχος means a technical inspection/check, especially of a vehicle.

It is not just any kind of check in the abstract. In a sentence about το αμάξωμα and ο κινητήρας, it clearly refers to a vehicle inspection.

So depending on context, it could be translated as:

• technical inspection
• vehicle inspection
• mechanical inspection

Because the subject is plural in meaning:

• το αμάξωμα
• και
• ο κινητήρας

These two things together form a compound subject, so the verb is plural.

That is why Greek uses:

• επιθεωρούνται = are inspected

and not singular επιθεωρείται.

Επιθεωρούνται is the present passive form of the verb επιθεωρώ.

• επιθεωρώ = I inspect
• επιθεωρούνται = they are inspected

Greek often uses the passive when the focus is on what is being inspected, not on who is doing the inspecting.

So this sentence emphasizes the car parts, not the inspector.

An active version would be something like:

• Στον τεχνικό έλεγχο οι τεχνικοί επιθεωρούν το αμάξωμα και τον κινητήρα.
• During the technical inspection, the technicians inspect the bodywork and the engine.

It is the 3rd person plural present passive form of επιθεωρώ.

A useful breakdown is:

• base verb: επιθεωρ-
• passive ending here: -ούνται / -ώνται pattern, giving επιθεωρούνται

Meaning:

• they are inspected

In this sentence, they refers to the bodywork and the engine.

Greek word order is more flexible than English word order.

This sentence starts with the setting:

• Στον τεχνικό έλεγχο = During the technical inspection

Then comes the verb:

• επιθεωρούνται = are inspected

Then the subject:

• το αμάξωμα και ο κινητήρας

This order is very natural in Greek, especially in more formal or informational language.

English usually prefers:

• The bodywork and the engine are inspected during the technical inspection.

Greek can also say that, but the given order is perfectly normal.

Because the two nouns have different grammatical genders.

• το αμάξωμα is neuter
• ο κινητήρας is masculine

So they take different articles:

• το for neuter singular nominative
• ο for masculine singular nominative

Both are subjects here, so they are in the nominative case.

Because many neuter nouns in Greek have the same form in the nominative and accusative singular.

So:

• το αμάξωμα can be nominative
• το αμάξωμα can also be accusative

In this sentence, it is nominative because it is part of the subject.

This can be confusing for English speakers, because the form alone does not tell you the case. You have to look at the role in the sentence.

Because ο κινητήρας is part of the subject, so it must be in the nominative.

Compare:

• ο κινητήρας = nominative, used for the subject
• τον κινητήρα = accusative, used for a direct object

In this sentence, the engine is not being used as a direct object of an active verb. It is one of the things that are being inspected, so it is the subject of the passive verb.

That is close to the Greek structure, but it is not natural English.

A more natural English translation would be:

• During the technical inspection, the bodywork and the engine are inspected.

or

• In the technical inspection, the bodywork and the engine are inspected.

The Greek structure is not unusual in Greek, but English usually prefers the subject before the verb.

No. σε is a very common preposition with a broad range of meanings. Depending on context, it can mean:

• in
• at
• to
• sometimes on

So στον τεχνικό έλεγχο could be understood as:

• in the inspection
• at the inspection
• during the inspection

In this sentence, during the inspection is probably the most natural English sense.

Yes, it sounds fairly formal or technical.

Words like:

• τεχνικός έλεγχος
• επιθεωρούνται

give it an official, procedural tone.

In everyday speech, someone might use simpler wording, but this sentence is very natural in contexts like:

• manuals
• official documents
• inspection procedures
• technical descriptions

A more active version could be:

• Στον τεχνικό έλεγχο ελέγχουν το αμάξωμα και τον κινητήρα.
• During the inspection, they check the bodywork and the engine.

Or, if you want to name the people doing it:

• Στον τεχνικό έλεγχο οι τεχνικοί επιθεωρούν το αμάξωμα και τον κινητήρα.

The original passive version is common when the process matters more than the person doing it.

A rough pronunciation guide is:

• Ston teh-khnee-KO EH-lehng-kho eh-pee-theh-o-ROON-deh to ah-MAK-so-ma keh o kee-nee-TEE-ras

A few notes:

• χ in τεχνικό and έλεγχο is like the ch in Scottish loch or German Bach
• αι in και sounds like e
• the stress is marked by the accent:
  • τεχνικό
  • έλεγχο
  • επιθεωρούνται
  • αμάξωμα
  • κινητήρας

If you want to sound natural, stress placement is very important in Greek.
