Mi ĉiam laŭdas mian fratinon, kaj post la ekzameno ni ĉiuj estis fieraj pri ŝi; mi ankoraŭ estas fiera pri ŝi nun.

Because fratinon is the direct object of laŭdas. In Esperanto, direct objects usually take -n.

Also, the adjective that goes with the noun must match it, so mia becomes mian.

• fratino = sister
• fratinon = sister as a direct object
• mia fratino = my sister
• mian fratinon = my sister as a direct object

So Mi ĉiam laŭdas mian fratinon means I always praise my sister, where my sister is the thing being praised.

Because adjectives agree with the nouns they describe in Esperanto.

Since fratinon is:

• singular
• accusative

the adjective must match:

• mian

If it were plural, both would change:

• mia fratino
• miaj fratinoj
• mian fratinon
• miajn fratinojn

This agreement is very regular in Esperanto.

Laŭdas is the present-tense form of laŭdi, which means to praise.

Esperanto verb endings are very regular:

• -i = infinitive, so laŭdi = to praise
• -as = present, so laŭdas = praise / am praising
• -is = past
• -os = future

So Mi ĉiam laŭdas... means I always praise...

Ĉiam means always. Its position is fairly flexible, but placing it after the subject is very natural.

So:

• Mi ĉiam laŭdas mian fratinon = very natural
• Ĉiam mi laŭdas mian fratinon = also possible, but with a different emphasis
• Mi laŭdas mian fratinon ĉiam = possible, but less neutral in many contexts

The version in the sentence sounds normal and straightforward.

Post means after.

So:

• post = after
• la ekzameno = the exam

Together, post la ekzameno means after the exam.

The preposition post does not require -n here, because it already shows the relationship clearly.

La is the definite article, meaning the.

In this sentence, la ekzameno suggests a specific exam that speaker and listener already know about. That is why the exam is used rather than just an exam.

Esperanto has only one article:

• la = the

There is no separate word for a or an.

Ni ĉiuj means we all.

• ni = we
• ĉiuj = all

So ni ĉiuj estis fieraj pri ŝi means we were all proud of her.

Using ĉiuj adds emphasis that every member of the group felt that way, not just some of them.

Yes, Esperanto allows some flexibility.

For example:

• Ni ĉiuj estis fieraj pri ŝi
• Ĉiuj ni estis fieraj pri ŝi

Both are possible. Ni ĉiuj is probably the most neutral and common here.

Because the adjective must match the subject.

In ni ĉiuj estis fieraj pri ŝi:

• subject = ni ĉiuj = we all
• plural subject, so adjective is plural
• fieraj = proud, plural

In mi ankoraŭ estas fiera pri ŝi nun:

• subject = mi = I
• singular subject, so adjective is singular
• fiera = proud, singular

So:

• mi estas fiera = I am proud
• ni estas fieraj = we are proud

Because the sentence talks about two different times.

• estis = past tense, were
• estas = present tense, am / are / is

So:

• post la ekzameno ni ĉiuj estis fieraj pri ŝi = after the exam, we were all proud of her
• mi ankoraŭ estas fiera pri ŝi nun = I am still proud of her now

The speaker is saying the pride existed in the past and continues into the present.

Pri usually means about, but with some words it is used in expressions that English translates differently.

Here, fiera pri means proud of.

So:

• fiera pri ŝi = proud of her

This is something you often just learn as a set expression:

• paroli pri = talk about
• pensi pri = think about
• fiera pri = proud of

Because pri is a preposition, and prepositions normally take the basic form, not the accusative.

So:

• ŝi = she / her after a preposition
• ŝin = her as a direct object

Compare:

• Mi vidas ŝin = I see her
• Mi estas fiera pri ŝi = I am proud of her

Since ŝi comes after pri, it stays ŝi, not ŝin.

Ankoraŭ means still.

So mi ankoraŭ estas fiera pri ŝi nun means I am still proud of her now.

It shows continuation: the feeling began earlier and has not stopped.

Without ankoraŭ, the sentence would simply say that the speaker is proud now. With ankoraŭ, it stresses that this is still true.

Nun means now. It adds extra clarity and emphasis.

• ankoraŭ = still
• nun = now

So the speaker is strongly contrasting:

• pride in the past
• pride at the present moment

You could say mi ankoraŭ estas fiera pri ŝi without nun, and it would still be correct. Adding nun just makes the time reference more explicit.

Yes. The semicolon separates two closely related ideas:

1. After the exam, we were all proud of her
2. I am still proud of her now

A comma could feel too weak, while a full stop would separate the thoughts more sharply. The semicolon shows that the two clauses are strongly connected.

This is mostly a punctuation choice, not a special grammar rule of Esperanto.

Esperanto pronouns do not change form after prepositions the way English pronouns do.

English has:

• she
• her

Esperanto has:

• ŝi for the basic form
• ŝin for the accusative

After a preposition like pri, Esperanto uses the basic form:

• pri ŝi = about her / of her

So even though English uses her, Esperanto uses ŝi because it is not a direct object.

These letters are often new for English speakers:

• ĉ sounds like ch in church
• ŝ sounds like sh in shoe
• ŭ is a short w-like sound, usually in diphthongs

So:

• ĉiam sounds roughly like CHEE-am
• ŝi sounds like shee
• laŭdas has aŭ, which sounds roughly like ow in now

So laŭdas is approximately LOW-das.

Because it is describing the subject, not the verb.

In mi estas fiera:

• mi is the subject
• estas is the linking verb
• fiera describes mi

That is why an adjective is used.

This is similar to English:

• I am proud not
• I am proudly

So Esperanto uses:

• fiera with mi
• fieraj with ni

Yes. That would also be correct.

Esperanto often allows different word orders for adverbs like ankoraŭ:

• mi ankoraŭ estas fiera pri ŝi
• mi estas ankoraŭ fiera pri ŝi

Both are fine. The version in the sentence is natural and clear. Adding nun gives a little extra emphasis to the present moment.
