Mi aŭskultas la instruistinon atente dum la leciono.

The -n marks the direct object.

In this sentence, mi is the subject, and la instruistinon is the person being listened to, so it gets the accusative ending -n.

A very important point for English speakers: Esperanto aŭskulti works like to listen to someone/something, but Esperanto usually does not use a separate word for to here. So:

• Mi aŭskultas la instruistinon = I listen to the female teacher

Even though English says listen to, Esperanto treats la instruistinon as a direct object.

It has several parts:

• instru- = teach
• -ist- = a person who does something as a profession or regular activity
• -in- = female
• -o = noun ending
• -n = direct object ending

So:

• instruisto = teacher
• instruistino = female teacher
• instruistinon = female teacher, as the direct object

This kind of word-building is very common in Esperanto.

La is the definite article, meaning the.

So la instruistinon means the female teacher, not just a female teacher.

Esperanto has:

• la = the
• no separate word for a/an

So:

• instruistino could mean a female teacher or just female teacher
• la instruistino means the female teacher

In this sentence, the speaker is probably referring to a specific teacher already known in the situation.

Because atente is an adverb, and it describes how the listening happens.

In Esperanto:

• -a = adjective
• -e = adverb

So:

• atenta = attentive
• atente = attentively

Here, it modifies the verb aŭskultas, not a noun:

• Mi aŭskultas ... atente = I listen ... attentively

If you said atenta, it would need to describe a noun, not the action.

Dum means during or while.

Here, dum la leciono means during the lesson.

It introduces a time expression:

• dum la leciono = during the lesson

This is the natural way to say that something happens throughout that time period.

Because la leciono means the lesson—a specific lesson.

In real context, this usually means the lesson currently happening or one already understood from the situation.

So:

• dum leciono = during a lesson
• dum la leciono = during the lesson

Both can be grammatical depending on meaning, but la leciono sounds more specific.

Esperanto distinguishes between hearing and listening, just like English does.

• aŭdi = to hear
• aŭskulti = to listen

So:

• Mi aŭdas la instruistinon = I hear the female teacher
• Mi aŭskultas la instruistinon = I listen to the female teacher

Aŭdi is more passive; aŭskulti is more active and intentional.

-as marks the present tense.

So:

• aŭskulti = to listen
• aŭskultas = listen / am listening / do listen

Esperanto present tense can cover several English present-time meanings, depending on context:

• I listen
• I am listening

Also, Esperanto verbs do not change for person:

• mi aŭskultas
• vi aŭskultas
• li aŭskultas
• ili aŭskultas

The ending stays -as for all persons.

Yes, Esperanto word order is fairly flexible.

The basic order here is:

• Mi = subject
• aŭskultas = verb
• la instruistinon = object
• atente = adverb
• dum la leciono = time phrase

But other orders are possible, especially for emphasis, for example:

• Atente mi aŭskultas la instruistinon dum la leciono.
• Dum la leciono mi aŭskultas la instruistinon atente.

Because instruistinon has the -n ending, you can still tell it is the object.

That said, the original order is very natural and easy to understand.

A rough pronunciation is ow-SKOOL-tahs.

A few useful details:

• aŭ sounds roughly like the ow in cow
• sk is pronounced clearly
• stress in Esperanto normally falls on the second-to-last syllable

So aŭs-kul-tas is stressed on kul:

• aŭsKULtas

Also, Esperanto pronunciation is very regular, so once you learn the sounds, words are usually pronounced exactly as written.

Normally, no.

With aŭskulti, Esperanto usually takes a direct object, so you say:

• Mi aŭskultas la instruistinon

not:

• Mi aŭskultas al la instruistino

This is one of those places where English and Esperanto structure differ. English says listen to, but Esperanto usually just uses the accusative object.

So it is best to learn aŭskulti iun = to listen to someone.
