Lundon mi iros al la banko post la laboro.

Because in Esperanto, words for days and dates often take the accusative -n to show time when something happens.

So Lundon means on Monday.

This is a very common pattern:

• Lundon = on Monday
• Marde = on Tuesday / Tuesday
• La 5-an de majo = on the 5th of May

Here, -n does not mean a direct object. It marks the time expression.

Because iros is the future tense of iri (to go).

Esperanto verb endings are very regular:

• iras = go / am going
• iris = went
• iros = will go
• irus = would go
• iru = go!
• iri = to go

So mi iros means I will go.

Because al means to or toward, showing movement in the direction of a place.

• Mi iros al la banko = I will go to the bank
• Mi estos en la banko = I will be in the bank

So:

• al = movement toward a destination
• en = location inside something

Since the sentence is about going to the bank, al is the correct choice.

Yes, very similarly. La is the definite article, meaning the.

So:

• banko = a bank / bank in general
• la banko = the bank

In this sentence, al la banko means to the bank. That could mean a specific bank already understood from context, or simply the bank as a known destination, much like English.

Esperanto uses la much like English the, though in some expressions Esperanto may use it where English does not.

Post la laboro means after work or more literally after the work.

In Esperanto, la is often used in expressions where English uses no article, especially when talking about something understood as part of normal daily life.

So post la laboro is a very natural way to say after work.

You may also sometimes see article-less expressions in Esperanto, but here post la laboro sounds standard and idiomatic.

Literally, laboro means work.

In this sentence, post la laboro is understood as after work, meaning after the working period or after finishing one’s work for the day.

So even though the literal noun is work, the phrase works much like English after work.

Yes, it could go elsewhere. Esperanto word order is fairly flexible.

These are all possible:

• Lundon mi iros al la banko post la laboro.
• Mi iros al la banko lundon post la laboro.
• Mi lundon iros al la banko post la laboro.

Putting Lundon first gives it a little emphasis, like On Monday, I’ll go to the bank after work.

So the first position is often used for topic, emphasis, or what the speaker wants to frame first.

No. In Esperanto, days of the week are normally not capitalized unless normal spelling rules require it, such as at the beginning of a sentence.

So:

• lundon = on Monday
• Lundon = capitalized here only because it starts the sentence

The same is true for months and most other common nouns.

Not exactly. It specifically means I will go to the bank on Monday after work.

The phrase al la banko focuses on the destination. It does not explicitly say whether the speaker goes inside, although that may be implied in real life.

If you specifically wanted to emphasize going inside, you might use a different wording, depending on context. But as written, the main idea is simply the destination: to the bank.

It naturally attaches to the whole action mi iros al la banko.

So the meaning is:

On Monday, I will go to the bank after work.

It does not normally mean something like the bank after work. The phrase post la laboro tells us when the going happens.

In other words:

• Lundon = on Monday
• post la laboro = after work

Both are time expressions modifying the action mi iros.

Yes, absolutely.

They answer different aspects of when:

• Lundon = which day?
• post la laboro = at what point in the day?

So the sentence gives two pieces of time information:

On Monday + after work

That is completely normal in Esperanto, just as it is in English.
