Ελέγχουμε τον εξοπλισμό κάθε μέρα.

Ελέγχουμε is the 1st person plural present form of ελέγχω.

So it means we check or we are checking.

In this sentence, because of κάθε μέρα (every day), the present tense is understood as a habitual action: we check every day.

Greek often drops subject pronouns because the verb ending already shows who is doing the action.

The ending -ουμε tells you the subject is we.

So:

• Ελέγχουμε = we check
• Εμείς ελέγχουμε = we check, but with extra emphasis on we

You would add εμείς only if you want contrast or emphasis.

Because τον εξοπλισμό is the direct object of the verb.

Greek changes nouns and articles depending on their role in the sentence.

• ο εξοπλισμός = the equipment as a subject (nominative)
• τον εξοπλισμό = the equipment as an object (accusative)

Since we check the equipment, equipment is what receives the action, so Greek uses the accusative.

Τον is the masculine singular accusative definite article, meaning the.

It matches εξοπλισμό in:

• gender: masculine
• number: singular
• case: accusative

So:

• ο εξοπλισμός = the equipment (subject form)
• τον εξοπλισμό = the equipment (object form)

This is a normal pattern for many masculine nouns ending in -ος.

For this type of noun:

• nominative singular: ο εξοπλισμός
• accusative singular: τον εξοπλισμό

So the ending changes from -ος to -ο when the noun is used as a direct object.

This is very common in Greek:

• ο άνθρωπος → τον άνθρωπο
• ο δρόμος → τον δρόμο
• ο εξοπλισμός → τον εξοπλισμό

Κάθε means each or every, and it normally goes with a singular noun.

So κάθε μέρα literally means each day, which in natural English is every day.

That is why Greek uses singular μέρα, not a plural form.

After κάθε, Greek normally uses the noun without the article.

So you say:

• κάθε μέρα = every day
• κάθε εβδομάδα = every week
• κάθε χρόνο = every year

Using an article here would not be the normal structure.

Yes. Greek word order is more flexible than English because case endings help show what each word is doing.

This sentence has a very neutral order:

• Ελέγχουμε τον εξοπλισμό κάθε μέρα.

But you could also say:

• Κάθε μέρα ελέγχουμε τον εξοπλισμό.
  This emphasizes every day.
• Τον εξοπλισμό τον ελέγχουμε κάθε μέρα.
  This puts special focus on the equipment.

So the original sentence is natural and straightforward, but it is not the only possible order.

Greek present tense can cover both ideas, depending on context.

• Ελέγχουμε can mean we check
• Ελέγχουμε can also mean we are checking

In this sentence, κάθε μέρα makes it clear that the meaning is habitual, so the best English translation is we check the equipment every day.

A rough English-friendly pronunciation is:

e-LENG-hoo-me ton ek-so-plee-ZMO KA-the ME-ra

A few notes:

• Ελέγχουμε has stress on -λέγ-
• εξοπλισμό has stress on the last syllable: -σμό
• κάθε has the th sound of think
• μέρα has stress on μέ-

The spelling stress marks in Greek are very important because they show which syllable is stressed.

Yes. Καθημερινά means daily / every day and is very natural.

So you could also say:

• Ελέγχουμε τον εξοπλισμό καθημερινά.

Both are correct:

• κάθε μέρα = every day
• καθημερινά = daily / every day

Κάθε μέρα is slightly more literal and conversational, while καθημερινά is a bit more compact.
