La dua raŭndo finiĝis per remizo.

Dua means second. In Esperanto, ordinal numbers are usually made by taking the basic number and adding -a:

• unu = one → unua = first
• du = two → dua = second
• tri = three → tria = third

Because raŭndo is a noun, dua works like an adjective and describes it: la dua raŭndo = the second round.

La is the definite article, meaning the.

In Esperanto, as in English, when you talk about a specific numbered item, you usually use the:

• la unua ĉapitro = the first chapter
• la dua raŭndo = the second round

So la dua raŭndo is the natural way to say the second round.

Raŭndo means round, especially in games, sports, competitions, or similar contexts.

It is a borrowed word adapted to Esperanto spelling. The aŭ is pronounced roughly like the ow in now, so raŭndo sounds approximately like ROUND-oh.

A learner might notice that this is not spelled like English round because Esperanto always uses its own regular spelling system.

A rough pronunciation guide:

• raŭndo ≈ ROW-n-do
  
  • aŭ sounds like ow in cow
• finiĝis ≈ fee-NEE-jis, but with ĝ sounding like the j in judge

More exactly:

• f as in English fine
• i always like ee in see
• ĝ like English j
• is is the normal past-tense ending

So finiĝis is approximately fee-NEE-jis.

Finiĝis means ended or more literally became finished.

This is an important Esperanto pattern:

• fini = to finish, to end
• fini ion = to finish something
• finiĝi = to become finished, to come to an end

So:

• Mi finis la libron. = I finished the book.
• La libro finiĝis. = The book ended / came to an end.

In your sentence, the subject is la dua raŭndo. The round is not actively finishing something else; rather, it itself came to an end. That is why finiĝis is used, not finis.

It has three parts:

• fin- = the root meaning end / finish
• -iĝ- = a suffix meaning become or get into a state
• -is = past tense

So:

fin-iĝ-is
= became ended
= ended / came to an end

This -iĝ- suffix is very common in Esperanto and often shows that something changes state by itself.

Here per shows the way or result by which the round concluded. In natural English, we would usually say ended in a draw, but Esperanto often uses finiĝi per ... = to end with ... / to conclude by ....

So:

• La kunveno finiĝis per aplauzoj. = The meeting ended with applause.
• La ludo finiĝis per remizo. = The game ended in a draw.

Even though per often means by means of, here it is best understood as part of the natural expression finiĝi per.

Because remizo comes after the preposition per, and nouns after prepositions normally do not take -n.

So:

• per remizo = with a draw / in a draw

The accusative -n is mainly used for:

1. the direct object
2. direction toward something in certain expressions

Neither of those applies here, so remizo stays in its basic -o form.

Remizo means draw or tie, especially in games, sports, chess, and competitions.

So if neither side wins, the result can be a remizo.

It is a standard Esperanto word in this context.

No, Esperanto word order is fairly flexible, though this sentence uses the most neutral order:

La dua raŭndo finiĝis per remizo.

That order is natural because it goes:

1. subject: la dua raŭndo
2. verb: finiĝis
3. prepositional phrase: per remizo

You could change the order for emphasis, but the original is the clearest and most ordinary way to say it.

You could use that to understand the grammar, but it is not good natural English.

A more literal grammatical breakdown is something like:

• La dua raŭndo = the second round
• finiĝis = became finished / ended
• per remizo = with a draw / by means of a draw

But the natural English meaning is simply:

The second round ended in a draw.

So the literal breakdown is useful for learning the structure, while the natural translation is what you would actually say in English.
