Κόβω το ακτινίδιο και το βάζω στο γιαούρτι μου.

They do two different jobs:

• το ακτινίδιο: here το is the definite article, meaning the.
• το βάζω: here το is a weak object pronoun, meaning it.

So:

• Κόβω το ακτινίδιο = I cut the kiwi
• και το βάζω... = and I put it...

Greek often repeats the object this way instead of just leaving it implied.

Κόβω is the 1st person singular present tense of κόβω, so it means I cut or I am cutting, depending on context.

Greek present tense can cover both:

• I cut
• I’m cutting

Unlike English, Greek does not need a separate am + -ing form here.

Because Greek is a language that often drops subject pronouns when they are already clear from the verb ending.

• Κόβω already means I cut / I’m cutting
• If you said Εγώ κόβω, that would add emphasis, like I cut.

So the sentence sounds natural without εγώ.

In Greek, weak object pronouns like το, τη(ν), τον, μου, σου usually come before the verb.

So Greek says:

• το βάζω = I put it

not a structure like:

• βάζω το

This is a very common Greek pattern:

• Τον βλέπω = I see him
• Τη θέλω = I want it/her
• Το κάνω = I do it

Βάζω is a very common verb meaning put, place, and in some contexts add.

In this sentence, το βάζω στο γιαούρτι μου most naturally means:

• I put it in my yogurt
• or I add it to my yogurt

Greek uses βάζω in many everyday expressions, so it is worth learning early.

Because στο is the contracted form of:

• σε + το = στο

Here:

• σε = in / to / into
• το γιαούρτι = the yogurt

So:

• στο γιαούρτι = in the yogurt / into the yogurt

This contraction is standard and very common:

• στο σπίτι = in the house / at home
• στο βιβλίο = in the book
• στο τραπέζι = on the table / at the table, depending on context

Greek σε is a very flexible preposition. Its exact meaning depends on the verb and context.

It can mean:

• to
• in
• into
• sometimes at or on

So in βάζω στο γιαούρτι, English prefers in/into the yogurt, but Greek simply uses σε.

This is normal: Greek and English do not always divide prepositions the same way.

μου means my, but in Greek possessive words like μου, σου, του, της usually come after the noun.

So:

• το γιαούρτι μου = my yogurt
• literally: the yogurt my

This is one of the biggest word-order differences from English.

More examples:

• το σπίτι μου = my house
• η φίλη μου = my friend
• το βιβλίο μου = my book

Because in Greek, possessives like μου normally go together with the definite article.

So Greek says:

• το γιαούρτι μου

not usually:

• γιαούρτι μου in this neutral context

This is very natural Greek:

• η μητέρα μου = my mother
• ο αδερφός μου = my brother
• το αυτοκίνητό μου / το αυτοκίνητο μου = my car

English drops the, but Greek usually keeps it.

Ακτινίδιο is neuter singular, which is why it takes:

• the article το
• the pronoun το

So:

• το ακτινίδιο
• το βάζω

Many Greek nouns ending in -ι or -ιο are neuter, though you should always learn each noun with its article.

Γιαούρτι is also neuter singular, so it takes:

• το γιαούρτι

This is why the sentence has:

• στο γιαούρτι μου = σε + το γιαούρτι μου

Since both ακτινίδιο and γιαούρτι are neuter, you see το with both of them.

Usually yes. In this sentence, και simply connects the two actions:

• Κόβω το ακτινίδιο
• και το βάζω στο γιαούρτι μου

So it works exactly like and here.

Greek και can also appear in other uses, but for a beginner, treating it as and is perfectly fine in this sentence.

It would sound incomplete or unnatural to most speakers, because βάζω normally needs its object to be expressed if it is important.

So Greek prefers:

• Κόβω το ακτινίδιο και το βάζω στο γιαούρτι μου.

That το clearly refers back to το ακτινίδιο.
Without it, the listener has to infer the object, and the sentence sounds less natural.

Not by itself. Κόβω broadly means cut. The exact result depends on context.

In this sentence, because you are cutting a kiwi and putting it into yogurt, the natural interpretation is something like:

• cutting it up
• slicing it
• chopping it into pieces

But the verb itself does not specify the exact shape of the pieces.

Greek word order is more flexible than English, but this version is the most neutral and natural:

• Κόβω το ακτινίδιο και το βάζω στο γιαούρτι μου.

You can move things around for emphasis, but beginners should learn this standard order first:

1. verb
2. object
3. και
4. object pronoun + verb
5. prepositional phrase

So yes, word order can change, but this sentence is the safest model to copy.

You could emphasize μου in speech, or use a slightly different structure depending on the context.

The basic sentence already means my yogurt:

• ...στο γιαούρτι μου

If you stress μου, it can imply:

• in my yogurt, not someone else’s

Greek often uses voice emphasis rather than changing the words dramatically. For a learner, the standard sentence is enough unless you specifically need contrast.

It is pronounced approximately ak-ti-NEE-thyo in standard modern Greek.

A few helpful points:

• the stress is on νί
• δ in modern Greek sounds like the th in this
• ιο at the end is pronounced together, roughly like yo

So a rough English-friendly guide is:

• ακτινίδιο → ak-ti-NEE-thyo

A rough pronunciation is ya-OOR-tee.

Helpful points:

• the stress is on ούρ
• για sounds roughly like ya
• τι at the end sounds like tee

So:

• γιαούρτι → ya-OOR-tee

Because Greek often uses the present tense for:

• habits
• routines
• instructions
• describing what someone is doing step by step

So Κόβω το ακτινίδιο και το βάζω στο γιαούρτι μου can sound like:

• something I usually do
• something I am doing now
• a simple description of a food-preparation step

The exact meaning comes from context, not from a special tense change.
