La paciento okupas la liton.

The -n is the accusative ending. In Esperanto, it usually marks the direct object of the verb.

• la paciento = the patient → the one doing the action
• la liton = the bed → the thing affected by the action

So in La paciento okupas la liton, the patient is occupying the bed, so lito becomes liton.

Because paciento is the subject, not the direct object.

In this sentence:

• La paciento = subject
• okupas = verb
• la liton = direct object

Only the direct object gets -n here, so paciento stays paciento, not pacienton.

The ending -as marks the present tense in Esperanto.

So:

• okupi = to occupy
• okupas = occupies / is occupying

Esperanto present tense often covers both English simple present and present progressive, depending on context.

La is the definite article in Esperanto, meaning the.

So:

• la paciento = the patient
• la liton = the bed

If the speaker means a specific patient and a specific bed, la is used. Esperanto uses the same article la for all nouns, regardless of gender, number, or case.

No. Esperanto has no indefinite article.

So:

• paciento = a patient / patient
• lito = a bed / bed
• la paciento = the patient
• la lito = the bed

That means Esperanto distinguishes definite nouns with la, but usually leaves indefinite nouns unmarked.

Not as strictly as in English. Esperanto word order is fairly flexible because the -n ending helps show what is the object.

So these can mean the same thing:

• La paciento okupas la liton.
• La liton okupas la paciento.

Both mean that the patient occupies the bed, because liton still has the object marking -n.

That said, subject–verb–object is the most neutral and common order, so La paciento okupas la liton is the most straightforward version.

Yes. In Esperanto, paciento is a noun meaning patient in the medical sense.

The ending -o marks a noun:

• paciento = patient
• lito = bed

If you want an adjective in Esperanto, it normally ends in -a. So learners should not assume English-looking words keep the same part of speech.

You learn it from usage: okupi is normally a transitive verb, meaning it acts directly on something.

So you occupy something:

• okupi la liton = to occupy the bed
• okupi ĉambron = to occupy a room

Because it takes a direct object, that object gets -n.

Yes, depending on context. Okupi can mean occupy, take up, or be using/in, depending on what is being talked about.

With lito (bed), it often suggests that the patient is in the bed or using the bed, not necessarily anything dramatic. The exact English wording can vary by context, even though the Esperanto grammar stays the same.

Add -j for plural nouns, and keep -n on a plural direct object if needed.

Examples:

• La pacientoj okupas la liton. = The patients occupy the bed.
• La paciento okupas la litojn. = The patient occupies the beds.
• La pacientoj okupas la litojn. = The patients occupy the beds.

Notice that a plural direct object gets both endings:

• litoj = beds
• litojn = beds as a direct object

A learner might expect English pronunciation, but Esperanto is much more regular.

A rough pronunciation is:

• pa-tsi-EN-to

A few useful points:

• c is pronounced like ts
• stress falls on the second-to-last syllable
• vowels are pronounced clearly and consistently

So paciento has stress on EN.
