Ο τεχνικός έλεγχος αρχίζει σήμερα.

Ο is the definite article meaning the for a masculine singular noun in the nominative case.

In this sentence, ο έλεγχος means the inspection / the check / the control.

Greek articles change for gender, number, and case, unlike English the, which never changes.

In Greek, adjectives often come before the noun, just as in English, so τεχνικός έλεγχος is the most neutral and common order.

• τεχνικός = technical
• έλεγχος = inspection / check

You can sometimes place the adjective after the noun in Greek, but that often sounds more formal, literary, or stylistically marked. For everyday usage, τεχνικός έλεγχος is the natural order.

Because it must agree with έλεγχος.

Greek adjectives agree with the noun they describe in:

• gender
• number
• case

Here, έλεγχος is:

• masculine
• singular
• nominative

So the adjective also appears in the masculine singular nominative form:

• τεχνικός

If the noun changed, the adjective would change too.

In Greek, every noun has a grammatical gender: masculine, feminine, or neuter. This is not always logical from an English point of view, because grammatical gender is part of the noun itself.

έλεγχος happens to be masculine, so it takes:

• the masculine article ο
• the masculine adjective form τεχνικός

This is something learners usually need to memorize along with the noun:

• ο έλεγχος

It is in the nominative case, because it is the subject of the sentence.

The sentence tells us what is beginning:

• Ο τεχνικός έλεγχος = the subject
• αρχίζει = begins
• σήμερα = today

So Greek uses the nominative for the thing doing the action of beginning.

αρχίζει is the third person singular present tense of the verb αρχίζω (to begin / to start).

So it means:

• he/she/it begins
• or, in this sentence, it begins, because the subject is ο τεχνικός έλεγχος

The ending -ει / -ίζει here shows the 3rd person singular present form.

Because the subject is singular:

• ο τεχνικός έλεγχος = the technical inspection

That is one inspection, not several. So the verb must also be singular:

• αρχίζει = begins

If the subject were plural, the verb would also be plural.

It can mean either, depending on context.

Greek present tense often covers both:

• begins
• is beginning
• sometimes even a general present like starts

In this sentence, the most natural English translation is usually begins today or starts today, but context could make is beginning today possible too.

Yes. In many contexts, αρχίζει can be translated as either begins or starts.

For this sentence, English speakers often prefer:

• The technical inspection starts today

But begins today is also completely correct.

Greek word order is more flexible than English word order because Greek uses case endings to show grammatical roles.

Putting σήμερα at the end is very natural and unmarked:

• Ο τεχνικός έλεγχος αρχίζει σήμερα.

It could also appear in another position, for example:

• Σήμερα αρχίζει ο τεχνικός έλεγχος.

That would put more emphasis on today.

So the sentence-final position here is simply the normal, neutral choice.

You do not pronounce the accent marks as separate sounds, but they show you which syllable is stressed.

In this sentence:

• τεχνικός → stress on the last syllable: te-khni-KOS
• έλεγχος → stress on the first syllable: E-len-khos
• αρχίζει → stress on the second syllable: ar-KHI-zi
• σήμερα → stress on the first syllable: SI-me-ra

So the accents are very important for correct pronunciation.

A rough pronunciation guide:

• έλεγχος ≈ EH-len-hos
• αρχίζει ≈ ar-HEE-zee

A few useful notes:

• χ is not like English ch. It is a throat sound, like the ch in German Bach or Scottish loch.
• γ before χ contributes to a nasal sound, so -γχ- is not pronounced exactly like simple -h-. In careful pronunciation, έλεγχος is closer to EH-len-ghos / EH-len-hos depending on how detailed you want to be.
• ζ in Modern Greek sounds like z.

For most learners, a good practical target is:

• EH-leng-hos
• ar-HEE-zee

Yes. σήμερα means today, and in this sentence it functions as an adverb of time.

It tells you when the action happens:

• αρχίζει = begins
• σήμερα = today

So it modifies the verb.

Because αρχίζει is already a complete verb meaning begins / starts.

English learners sometimes look for an extra verb like is, but Greek does not need one here. The sentence structure is simply:

• subject
  • verb
    • time expression

So:

• Ο τεχνικός έλεγχος = subject
• αρχίζει = verb
• σήμερα = adverb of time

Yes, absolutely.

Greek allows this order too:

• Αρχίζει σήμερα ο τεχνικός έλεγχος.

This sounds natural and may place a little more focus on the action or on the timing. Greek often changes word order for emphasis, rhythm, or style.

So both are correct, but:

• Ο τεχνικός έλεγχος αρχίζει σήμερα. = neutral, straightforward
• Αρχίζει σήμερα ο τεχνικός έλεγχος. = slightly more emphasis on begins today

It is better to learn it as ο έλεγχος.

That helps you remember:

• the noun’s gender (masculine)
• the correct article
• how adjectives will agree with it

This is a very good habit in Greek, because gender matters throughout the language.

It can be both.

As an adjective:

• τεχνικός έλεγχος = technical inspection

As a noun:

• ο τεχνικός = the technician

That is very common in Greek. Many adjective forms can also function as nouns when the noun they refer to is understood from context.

So in this sentence, τεχνικός is clearly an adjective because it describes έλεγχος.

A few key points:

1. Article + noun gender

   • ο έλεγχος is masculine

2. Adjective agreement

   • τεχνικός matches έλεγχος

3. Present tense verb

   • αρχίζει = begins / starts

4. Flexible word order

   • Greek can move pieces around more easily than English

5. Stress marks

   • They matter for pronunciation

This sentence is short, but it shows several core Greek grammar patterns very clearly.
