Ni nepre ludos la tabulludon.

In Esperanto, -os is the future-tense ending for verbs. So ludos means will play.

Esperanto verb endings are very regular:

• -as = present: ludas = play / are playing
• -is = past: ludis = played
• -os = future: ludos = will play
• -us = conditional: ludus = would play
• -u = command/wish: ludu = play!

So Ni nepre ludos... means that the action is in the future.

Nepre means something like definitely, for sure, certainly, or without fail.

It adds a strong sense of certainty or determination. In this sentence, it suggests that playing the board game is not just a possibility—it is something that will definitely happen.

So Ni nepre ludos la tabulludon has a stronger tone than just:

• Ni ludos la tabulludon = We will play the board game
• Ni nepre ludos la tabulludon = We will definitely play the board game

The -n marks the direct object in Esperanto.

Here, la tabulludon is the thing being played, so it gets the accusative ending -n:

• Ni ludos la tabulludo would be incorrect
• Ni ludos la tabulludon is correct

This is one of the most important features of Esperanto grammar: the noun receiving the action often takes -n.

Compare:

• Mi vidas la hundon = I see the dog
• Ŝi manĝas pomon = She is eating an apple
• Ni ludos la tabulludon = We will play the board game

La is the definite article in Esperanto, meaning the.

So:

• tabulludo = a board game / board game
• la tabulludo = the board game

In your sentence, la shows that a specific board game is meant, not just any board game in general.

Unlike English, Esperanto has only one article, la. There is no separate word for a/an.

It is made from smaller parts:

• tabul- = board
• lud- = play/game
• -o = noun ending
• -n = direct object ending

So:

• tabulludo = board game
• tabulludon = board game as a direct object

This kind of word-building is very common in Esperanto. You can often understand long words by breaking them into roots and endings.

In Esperanto, verbs do not change depending on the subject.

So the verb form stays the same whether the subject is I, you, he, she, we, or they.

For example:

• Mi ludos = I will play
• Vi ludos = you will play
• Ni ludos = we will play
• Ili ludos = they will play

That makes Esperanto much simpler than English in some ways, because you do not need to memorize different verb forms like I am / you are / he is.

Yes, Esperanto word order is fairly flexible, especially because the -n ending helps show what the object is.

The normal, neutral order here is:

• Ni nepre ludos la tabulludon

But other orders are possible for emphasis, such as:

• La tabulludon ni nepre ludos
• Nepre ni ludos la tabulludon

These can sound more emphatic or stylistically marked. For a learner, though, the standard order subject + adverb + verb + object is the safest and most natural choice.

Nepre is an adverb, so it can move around more than the main sentence parts can.

In Ni nepre ludos la tabulludon, it comes before the verb, which is very natural. That placement makes it clear that it modifies the whole action of playing.

You may also see:

• Ni ludos nepre la tabulludon
• Nepre ni ludos la tabulludon

These are possible, but Ni nepre ludos... is a very straightforward and common placement.

Esperanto stress is very regular: it always falls on the second-to-last syllable of a word.

So:

• Ni = just ni
• nepre = NE-pre
• ludos = LU-dos
• la = la
• tabulludon = ta-bul-LU-don

A rough pronunciation guide:

• Ni ≈ nee
• nepre ≈ NEH-preh
• ludos ≈ LOO-dohs
• la ≈ lah
• tabulludon ≈ tah-bool-LOO-dohn

So the whole sentence is roughly:

nee NEH-preh LOO-dohs lah tah-bool-LOO-dohn

Yes. Ludi means to play, especially in the sense of playing a game.

So:

• ludi ŝakon = to play chess
• ludi kartludon = to play a card game
• ludi tabulludon = to play a board game

That is why no extra preposition is needed here. Esperanto simply uses ludi plus a direct object.

Yes, tabulludo is a normal and understandable compound word for board game.

It literally means something like board-play/game. Esperanto often forms vocabulary this way by combining roots. Even if a learner has never seen the exact word before, it is usually easy to figure out from its parts.

So this sentence is also a good example of how Esperanto builds words transparently.
