La urbo donis al ni permeson por la evento.

La means the, so La urbo means the city.

In Esperanto, you use la when you are talking about a specific, identifiable thing. Here, it is not just any city, but a particular city authority that gave permission.

Also, urbo literally means city, but in sentences like this it often stands for the city government / the municipal authorities, just as English can say The city gave us permission.

In Esperanto, -is marks the past tense.

So:

• doni = to give
• donas = gives / is giving
• donis = gave
• donos = will give

So La urbo donis... means The city gave...

Al means to.

So:

• ni = we
• al ni = to us

In this sentence, the permission was given to us, so Esperanto uses al to mark the recipient:

• La urbo donis al ni permeson = The city gave permission to us

This is very common with verbs like doni (to give).

The -n ending marks the direct object in Esperanto.

Here, permeson is the thing that was given. The city gave permission, so permission is the direct object.

Compare:

• La urbo donis al ni permeso ❌
• La urbo donis al ni permeson ✅

A quick way to think about it: Ask What did the city give?
Answer: permission → so it takes -n.

Because ni is not the direct object here.

In this sentence:

• permeson = direct object, so it gets -n
• al ni = indirect object, introduced by al, so it does not get -n

Esperanto usually marks the indirect object with al, not with the accusative.

Por usually means for.

So por la evento means for the event.

It tells us what the permission is connected with: the permission was for holding, organizing, or carrying out the event.

Because evento comes after the preposition por.

Normally, nouns after prepositions do not take -n unless there is a special reason involving movement or direction. Here, por la evento is just a prepositional phrase meaning for the event, so evento stays without -n.

That is why:

• por la evento ✅
• por la eventon ❌

Yes. Esperanto can express this idea in two natural ways:

• La urbo donis al ni permeson por la evento.
• La urbo permesis al ni la eventon or, more naturally in many contexts, La urbo permesis al ni okazigi la eventon.

The version with doni permeson literally means give permission, which is very close to English and very natural.

Sometimes permesi needs a bit more structure to sound precise, especially if you want to say exactly what was permitted. That is one reason doni permeson can feel especially clear.

The sentence is in a very normal Esperanto word order:

La urbo | donis | al ni | permeson | por la evento

That is basically:

subject | verb | indirect object | direct object | extra phrase

Because Esperanto marks grammar clearly with al and -n, the word order can be changed more freely than in English. But this version is straightforward and easy to understand.

For example, these are also possible:

• La urbo donis permeson al ni por la evento.
• Al ni la urbo donis permeson por la evento.

They are grammatical, but the original order is the most neutral.

Yes, permeso means permission.

Related forms include:

• permesi = to permit / allow
• permeso = permission
• permesita = permitted / allowed
• sen permeso = without permission

So in this sentence, permeson is simply the accusative form of permeso.

Esperanto often has both options, just like English.

English can say:

• The city gave us permission for the event
• The city allowed us to hold the event

Esperanto works similarly:

• La urbo donis al ni permeson por la evento
• La urbo permesis al ni okazigi la eventon

The noun phrase doni permeson is common, natural, and sometimes slightly more formal or administrative in tone, which fits well with something a city government might do.
