Το παιδί κάθεται πάντα στο ίδιο καρεκλάκι όταν τρώει ή ζωγραφίζει.

Greek often leaves subject pronouns out because the verb ending already shows the person and number.

• κάθεται = he/she/it sits / is sitting
• τρώει = he/she/it eats / is eating
• ζωγραφίζει = he/she/it draws / is drawing

Since the sentence already begins with Το παιδί (the child), Greek does not need to repeat it or the child again in the later verbs.

Κάθεται means sits or is sitting.

It comes from the verb κάθομαι, which is the normal Modern Greek verb for sit. Even though its form looks like a middle/passive-type verb, here it is not passive in meaning. It simply means:

• Το παιδί κάθεται = The child sits / is sitting

In this sentence, because πάντα is also present, the meaning is habitual: the child always sits...

Greek uses the definite article much more often than English.

So Το παιδί is the natural way to say:

• the child
• or sometimes simply the child in question / the child we are talking about

If you said just παιδί, it would sound less complete here. In a normal full sentence, Greek usually wants the article with a noun like this.

Πάντα means always. Greek adverbs are fairly flexible, but this position is very natural:

• Το παιδί κάθεται πάντα...

It places always close to the verb it modifies. You could move πάντα in some contexts, but that would usually change emphasis rather than basic meaning.

So this word order is simply a normal, idiomatic way to say it.

Στο is the contracted form of σε το.

• σε = in, on, at, to
• το = the (neuter singular)

So:

• σε το ίδιο καρεκλάκι → στο ίδιο καρεκλάκι

This contraction is standard and expected in normal Greek.

Other common contractions are:

• στον = σε τον
• στη / στην = σε τη(ν)

In Modern Greek, σε is a very broad preposition. Depending on context, it can mean:

• in
• on
• at
• sometimes to

With furniture like a chair, English says sit on a chair, but Greek naturally uses σε:

• κάθεται στο καρεκλάκι = sits on/in the little chair

So this is just a difference between the two languages. You should not expect a one-to-one match with English prepositions.

Because ίδιο has to agree with καρεκλάκι.

Καρεκλάκι is:

• neuter
• singular

So the adjective must also be neuter singular:

• ίδιο καρεκλάκι = same little chair

The other forms would be used with different genders:

• ίδιος for masculine
• ίδια for feminine

Here, ίδιο is the correct matching form.

Because same normally refers to a specific, identifiable thing, so Greek uses the definite article naturally here.

• στο ίδιο καρεκλάκι = in/on the same little chair

This is like English: we also say the same chair, not same chair by itself in a full sentence.

So the structure is perfectly parallel in that sense:

• στο = in/on the
• ίδιο = same
• καρεκλάκι = little chair

Καρεκλάκι means little chair or small chair.

It comes from καρέκλα (chair) plus the diminutive ending -άκι, which often adds the idea of:

• small size
• affection
• something cute or child-sized

So καρεκλάκι could suggest:

• a small chair
• a child’s chair
• a cute little chair

In this sentence, that fits very well with το παιδί.

Because Greek uses the present tense for habitual actions, just like English does.

The sentence is describing what the child usually does, not just one single moment:

• κάθεται πάντα = always sits
• όταν τρώει ή ζωγραφίζει = when eating or drawing / whenever the child eats or draws

So the present tense here expresses repeated, regular behavior.

Όταν means when. In sentences about repeated or general situations, Greek commonly uses όταν + present tense.

So:

• όταν τρώει = when(ever) he/she eats
• όταν ζωγραφίζει = when(ever) he/she draws

In this sentence, the meaning is not one specific occasion, but a routine. That is why the present tense fits naturally.

Because it is understood to be the same subject: the child.

So Greek does not need to say:

• όταν το παιδί τρώει ή το παιδί ζωγραφίζει

That would be unnecessarily repetitive. Once Το παιδί has been introduced, the later verbs are automatically understood to refer to it unless the sentence signals a change of subject.

Because both verbs belong to the same when clause:

• όταν τρώει ή ζωγραφίζει = when it eats or draws

Greek, like English, does not need to repeat when before the second verb if the structure is shared.

So this means:

• when the child eats
• or when the child draws

Both actions are linked under the same time condition.

It can mean draws, paints, or more generally does art / colors / makes pictures, depending on context.

In everyday use with children, ζωγραφίζω often covers a broad range of picture-making activities. So in this sentence, English could translate it as:

• draws
• is drawing
• sometimes colors or paints, depending on the situation

If you were translating for a learner, draws is usually the safest basic choice.

It describes a general habit.

The clues are:

• πάντα = always
• present tense verbs
• όταν introducing a repeated situation

So the sentence is not mainly about one specific scene happening right now. It describes what the child regularly does: the child uses that same little chair whenever eating or drawing.
