Post la kunveno mi iros al la banko.

In Esperanto, -os is the future tense ending for verbs.

• iri = to go
• iras = go / am going
• iris = went
• iros = will go

So mi iros means I will go.

Mi iros is the most neutral and common word order: subject + verb.

Esperanto word order is fairly flexible, so Iros mi al la banko is possible in special contexts, but it sounds marked or emphatic. For a normal sentence, learners should use Mi iros.

Post is a preposition meaning after.

In this sentence, Post la kunveno means after the meeting. It introduces a time expression telling you when the action happens.

So the sentence structure is:

• Post la kunveno = after the meeting
• mi iros = I will go
• al la banko = to the bank

La is the Esperanto definite article, meaning the.

So:

• kunveno = meeting
• la kunveno = the meeting

It is used when the speaker has a specific meeting in mind, or when the meeting is already known from context.

For the same reason: la means the.

• banko = bank
• la banko = the bank

In practice, Esperanto often uses la much like English does. If the speaker means a particular bank, or the bank is understood from context, la is natural.

Kunveno is a noun meaning meeting.

It can also be understood from its parts:

• kun- = together
• veni = to come
• kunveni = to come together, assemble
• kunveno = a meeting, gathering

This is very typical Esperanto word-building.

Because -o is the noun ending in Esperanto.

All basic nouns end in -o, for example:

• banko = bank
• kunveno = meeting
• domo = house

This makes parts of speech very easy to recognize.

Because al means to, and it shows direction or destination.

• mi iros al la banko = I will go to the bank

If you said only mi iros la bankon, that would be wrong in normal Esperanto. The verb iri usually takes a destination with a preposition such as al.

Because al already shows the direction.

In Esperanto, the -n ending is used for direct objects, and sometimes for direction with certain expressions. But when you already have a directional preposition like al, you normally do not add -n.

So:

• correct: al la banko
• not normally: al la bankon

Yes. A comma after an introductory phrase like Post la kunveno is optional and often helpful for readability.

So both are acceptable:

• Post la kunveno mi iros al la banko.
• Post la kunveno, mi iros al la banko.

Yes, Esperanto allows some flexibility in word order.

For example, these are possible:

• Post la kunveno mi iros al la banko.
• Mi iros al la banko post la kunveno.

Both mean essentially the same thing. The version with Post la kunveno first gives a little more emphasis to the time.

Sometimes, yes. English speakers may mix up banko and benko.

• banko = bank
• benko = bench

So in this sentence, la banko definitely means the bank, not the bench.

A rough pronunciation is:

post la koon-VEH-no mee EE-ros ahl la BAHN-ko

A few helpful points:

• kunveno has stress on VE: kun-VE-no
• iros has stress on I: I-ros
• banko has stress on BAN: BAN-ko

In Esperanto, the stress is almost always on the second-to-last syllable.
