Se ĉi tiu presilo denove ne funkcios, mi portos la dosieron al alia ĉambro.

Se means if. It introduces a condition:

• Se ĉi tiu presilo denove ne funkcios... = If this printer does not work again...

This is the normal Esperanto word for conditional if in sentences like this.

ĉi tiu means this.

It is made from:

• tiu = that / that one
• ĉi = a particle that brings the meaning closer, giving this

So:

• tiu presilo = that printer
• ĉi tiu presilo = this printer

You may also see tiu ĉi presilo, which means the same thing. ĉi tiu is very common.

The ending -ilo often means a tool, instrument, or device used for doing something.

Here:

• presi = to print
• presilo = printer literally, a printing device

This is a very regular feature of Esperanto word-building.

Other examples:

• tranĉi = to cut → tranĉilo = knife
• skribi = to write → skribilo = writing tool, pen/pencil

The ending -os marks the future tense.

So:

• funkcias = works / is working
• funkciis = worked
• funkcios = will work

In this sentence:

• ne funkcios = will not work

Even though English often says If this printer doesn’t work again..., Esperanto can naturally use the future here because the whole situation is about a future possibility.

Funkcii means to function, to work. For machines, this is very common and natural.

So:

• La presilo ne funkcias. = The printer isn’t working.

This does not necessarily mean the printer is permanently broken. It just means it is not functioning properly.

A learner may expect a more specific verb, but funkcii is very idiomatic for machines and devices.

Ne usually goes directly before the word or phrase it negates.

Here:

• denove ne funkcios = will not work again

So ne negates the verb funkcios.

Compare:

• La presilo funkcios. = The printer will work.
• La presilo ne funkcios. = The printer will not work.

Denove means again.

So:

• denove ne funkcios = doesn’t work again / will not work again

In context, it suggests repetition: the printer has already failed before, and the speaker is talking about it failing once more.

Portos is the ordinary future tense: will carry / will take.

• mi portos = I will take
• mi portus = I would take

Because the sentence describes a real future possibility after a condition, Esperanto commonly uses -os in both parts:

• Se ... ne funkcios, mi portos ...
• If ... doesn’t work, I’ll take ...

You use -us more for more hypothetical, less direct, or contrary-to-fact ideas.

The ending -n marks the direct object.

Here:

• la dosiero = the file
• la dosieron = the file as the thing being carried

In mi portos la dosieron:

• mi = subject, the person doing the action
• la dosieron = direct object, the thing being taken

This -n ending is one of the most important parts of Esperanto grammar.

Because al means to, and after a preposition like al, you normally do not use -n just to mark the object.

So:

• al alia ĉambro = to another room

The accusative -n can sometimes show direction without a preposition:

• Mi iras hejmen. = I’m going home.
• Mi iras en la ĉambron. = I go into the room.

But here the sentence uses the clear preposition al, so alia ĉambro stays without -n.

Alia means other or another.

So:

• alia ĉambro = another room / a different room

This is different from dua, which means second.

Compare:

• alia ĉambro = another room, some different room
• dua ĉambro = second room

Yes. Esperanto word order is fairly flexible, but this sentence uses a very normal and clear order:

• Se ĉi tiu presilo denove ne funkcios, mi portos la dosieron al alia ĉambro.

This is basically:

• condition first
• main result second

That is the most natural order here. Because Esperanto marks grammar clearly with endings like -n, some rearrangement is possible, but learners should usually stick to the more standard order unless they have a reason to emphasize something.

Yes. Porti means to carry, wear, bear, and in many contexts it can also match English take when you physically bring something somewhere.

Here:

• mi portos la dosieron al alia ĉambro = I will take the file to another room

It suggests physically carrying or bringing the file. If the context were more about sending a digital file, a different verb would probably be used.

A rough guide:

Se ĉi tiu presilo denove ne funkcios, mi portos la dosieron al alia ĉambro.

Approximate pronunciation: seh chee TEE-oo preh-SEE-lo deh-NO-veh neh foonk-TSEE-os, mee POR-tos lah doh-see-EH-ron al ah-LEE-ah CHAHM-bro

A few useful points:

• ĉ sounds like ch in church
• ci in funkcios sounds like tsee
• stress is always on the second-to-last syllable
  • pre-SI-lo
  • funk-CI-os
  • do-si-E-ro
  • ĈAM-bro

It could, but it may sound less clear or may slightly change the emphasis.

• denove ne funkcios most naturally means won’t work again
• ne funkcios denove can sound more like won’t function again / won’t function any more

In practice, the original version is a very natural way to express if this printer doesn’t work again.

Yes. In Esperanto, a comma is normally used to separate a subordinate clause from the main clause.

So in:

• Se ĉi tiu presilo denove ne funkcios, mi portos la dosieron al alia ĉambro.

the comma separates:

1. the if-clause
2. the main clause

That is standard and helpful punctuation.
