Mia onklino ĉiam kunportas kukon, kiam ŝi venas al nia hejmo.

Mia means my. In Esperanto, possessive words like mia, via, lia, ŝia, nia, ilia behave like adjectives, so they end in -a.

So:

• mia onklino = my aunt
• nia hejmo = our home

Because they are adjective-like words, they can also change form if needed, just like adjectives do.

Esperanto often builds related words from one root.

• onklo = uncle
• onklino = aunt

The part -in- is the feminine suffix. It makes a female version of a person or animal word.

Examples:

• patro = father
• patrino = mother
• frato = brother
• fratino = sister

So onklino is literally something like female uncle, which is how Esperanto forms aunt.

Ĉiam means always.

It is an adverb, so it describes how often something happens. In this sentence, it modifies kunportas:

• Mia onklino ĉiam kunportas kukon = My aunt always brings a cake

Esperanto word order is fairly flexible, so ĉiam can sometimes move, but the position here is very natural and clear.

Kunportas comes from:

• kun- = with
• port- = carry, bring
• -as = present tense

So kunporti literally means to carry with oneself or to bring along.

In this sentence, kunportas kukon means brings a cake along.

This is a very common way Esperanto builds words: a small prefix plus a root.

The -n marks the direct object. The cake is the thing being brought, so it gets the accusative ending.

• kuko = cake
• kukon = cake as the direct object

Compare:

• Ŝi manĝas kukon. = She is eating a cake.
• Ŝi kunportas kukon. = She brings a cake.

In Esperanto, the direct object usually takes -n.

Esperanto has only one article: la, which means the.

There is no separate word for a/an. So:

• kuko can mean a cake or just cake, depending on context
• la kuko means the cake

Here, kukon is fine because the sentence does not need to specify a particular cake. It just means she brings a cake.

Because this sentence describes a habitual or general action.

• kunportas = brings
• venas = comes

In Esperanto, the present tense -as is often used for things that regularly happen:

• Kiam ŝi venas... = When she comes...
• Mia onklino ĉiam kunportas... = My aunt always brings...

This is similar to English using the simple present for habits:

• She always brings
• When she comes

Kiam means when.

It introduces a time clause:

• kiam ŝi venas al nia hejmo = when she comes to our home

So the sentence has two parts:

1. Mia onklino ĉiam kunportas kukon
2. kiam ŝi venas al nia hejmo

The second part tells when the first thing happens.

In Esperanto, subordinate clauses are often separated with a comma, especially when that makes the sentence easier to read.

So:

• Mia onklino ĉiam kunportas kukon, kiam ŝi venas al nia hejmo.

The comma marks the start of the kiam clause. In English, you might or might not use a comma in a similar sentence, but in Esperanto this punctuation is very normal.

Yes. Ŝi means she.

Esperanto pronouns include:

• mi = I
• vi = you
• li = he
• ŝi = she
• ĝi = it
• ni = we
• ili = they

The letter ŝ is pronounced like English sh, so ŝi sounds like shee.

Because al shows movement toward a place.

• al = to, toward
• en = in, inside

So:

• ŝi venas al nia hejmo = she comes to our home
• ŝi estas en nia hejmo = she is in our home

This is an important difference:

• use al for direction
• use en for location

Yes, in some contexts Esperanto can use hejmen, which means homeward / home with motion.

For example:

• Ŝi venas hejmen. = She comes home.

But al nia hejmo is more explicit: it clearly says to our home. Since this is our home, the phrase al nia hejmo is a very natural choice.

Because the phrase is governed by the preposition al.

After a preposition, you normally do not add -n just for direct object marking, because the preposition already shows the word’s role.

So:

• al nia hejmo = to our home

Here, hejmo is not a direct object; it is the object of the preposition al.

Also, nia matches hejmo as an adjective-like possessive, so it stays nia here.

The given word order is very natural, but Esperanto is more flexible than English because endings show grammatical roles.

This version is standard:

• Mia onklino ĉiam kunportas kukon, kiam ŝi venas al nia hejmo.

You might also see slight variations for emphasis, such as moving ĉiam, but beginners should usually follow the normal pattern:

• subject
• adverb
• verb
• object
• subordinate clause

So this sentence is a good model to imitate.

It breaks down like this:

• Mia onklino = subject
• ĉiam = adverb
• kunportas = main verb
• kukon = direct object
• kiam ŝi venas al nia hejmo = time clause

So the pattern is:

Subject + adverb + verb + object + time clause

That makes it a very useful example sentence for studying several basic Esperanto features at once.
