Ελέγχω το τακάκι, τη ζάντα και την ακτίνα.

Ελέγχω is the 1st person singular present tense of the verb ελέγχω, so it means I check / I inspect.

Greek often leaves out the subject pronoun, so Ελέγχω by itself already means I check. You could say Εγώ ελέγχω... for extra emphasis, but normally Greek does not need εγώ here.

They match the gender and case of each noun.

• το τακάκι → neuter singular
• τη ζάντα → feminine singular
• την ακτίνα → feminine singular

All three nouns are the direct objects of Ελέγχω, so they are in the accusative case.

In this sentence:

• το = accusative singular article for a neuter noun
• τη(ν) = accusative singular article for a feminine noun

So the article changes depending on the noun it goes with.

This is a very common point in Modern Greek.

The feminine accusative article is basically την, but the final -ν is often dropped before certain consonants.

So:

• τη ζάντα is normal, because ζάντα starts with ζ
• την ακτίνα keeps the -ν, because ακτίνα starts with a vowel

A simple learner-friendly rule is:

• keep -ν before vowels
• also usually keep it before sounds like κ, π, τ, ξ, ψ and consonant clusters built from them
• often drop it before many other consonants

That is why you see both τη and την in the same sentence.

Greek usually repeats the article with each noun when the nouns are definite and listed separately.

So Greek naturally says:

• το τακάκι, τη ζάντα και την ακτίνα

rather than using one article to cover all three.

This is very normal Greek structure. In English, we often say the pad, rim, and spoke with only one the, but Greek commonly repeats the article.

Yes. They are the direct objects of the verb Ελέγχω, so they are in the accusative.

You can tell mainly from the articles:

• το can be nominative or accusative for neuter singular
• τη(ν) is the feminine singular accusative article

The noun forms themselves do not change much here:

• τακάκι looks the same in nominative and accusative
• ζάντα also looks the same in nominative and accusative
• ακτίνα also looks the same in nominative and accusative

So in this sentence, the article is the clearest clue.

They are:

• το τακάκι → neuter
• η ζάντα → feminine
• η ακτίνα → feminine

A learner should memorize nouns together with their article, because the article tells you the gender:

• το τακάκι
• η ζάντα
• η ακτίνα

That is much better than learning just the bare noun by itself.

Yes, -άκι is a very common Greek diminutive ending, and τακάκι historically has that shape.

In Modern Greek, though, words with diminutive endings are not always felt as strongly diminutive in everyday use. Sometimes they are just the normal word for an object.

So a learner may notice the ending -άκι, but in a sentence like this it is best to learn το τακάκι simply as the standard noun being used here.

Yes, you could say Εγώ ελέγχω το τακάκι, τη ζάντα και την ακτίνα.

It is grammatically correct, but it sounds more emphatic because εγώ is added explicitly. It can suggest something like:

• I am the one checking them
• or a contrast, such as I check them, not someone else

Without εγώ, the sentence is the more neutral, natural version.

A simple pronunciation guide is:

• Ελέγχω → e-LENG-ho
• το τακάκι → to ta-KA-ki
• τη ζάντα → ti ZAN-da
• και → ke
• την ακτίνα → tin ak-TI-na

A few helpful notes:

• γχ in ελέγχω sounds like a nasal + rough h/ch sound, not like English g-h
• ζ sounds like z
• αι in και sounds like e

The written accent mark shows which syllable is stressed.

The sentence as written is a very natural, neutral order:

• Ελέγχω το τακάκι, τη ζάντα και την ακτίνα.

Greek word order is more flexible than English, so other orders are possible, especially for emphasis. For example, you could move the object phrase earlier in some contexts.

But for a learner, the given order is the safest and most standard one to use. It is clear, natural, and very common in everyday Greek.
