Kesho jioni, mimi na Juma tutaangalia sanaa za mitaani mjini.

Because Swahili very often puts time expressions near the beginning of the sentence.

• kesho = tomorrow
• jioni = evening

Together, kesho jioni means tomorrow evening.

Starting with the time phrase is very natural in Swahili, just like saying Tomorrow evening, ... in English.

They give different pieces of time information:

• kesho = tomorrow
• jioni = in the evening

So:

• kesho alone = tomorrow
• jioni alone = in the evening
• kesho jioni = tomorrow evening

Using both makes the time more specific.

Good question. The verb tutaangalia already contains tu-, which means we. So the subject is already built into the verb.

However, mimi na Juma is added for clarity or emphasis, especially because the speaker wants to say exactly who we are.

So:

• tutaangalia = we will look/watch
• mimi na Juma tutaangalia = Juma and I will look/watch

This is very normal in Swahili. Pronouns or full subject nouns are often added even when the verb already shows the subject.

Yes, absolutely.

Both are understandable:

• mimi na Juma
• Juma na mimi

In many situations, Juma na mimi may sound a little more natural or polite to an English speaker, since English often puts the other person first. But mimi na Juma is also perfectly valid Swahili.

It breaks down like this:

• tu- = we
• -ta- = future tense marker (will)
• angalia = look at / watch

So:

• tutaangalia = we will look at / we will watch

This is a very useful Swahili pattern:

• nitaangalia = I will look/watch
• utaangalia = you will look/watch
• tutaangalia = we will look/watch

Because in Swahili, angalia normally takes its object directly.

In English, we say:

• look at the art

But in Swahili, you simply say:

• kuangalia sanaa

So angalia works more like look at as a single idea. You do not need an extra word for at.

This phrase can be understood literally as something like art(s) of the streets, which is why the meaning comes out as street art.

Here is the structure:

• sanaa = art / artworks
• za = an agreement word meaning of for this noun class/plural sense
• mitaani = in the streets / on the streets

So sanaa za mitaani means street art or more literally artworks of the streets.

The word za is there because Swahili uses agreement between nouns and connecting words. English does not do this in the same way, so it often feels unfamiliar at first.

Because the connector must agree with the noun sanaa as it is being used here.

Swahili has noun classes, and words connected to a noun often change form to match that noun. In this sentence, sanaa is being treated in a plural/collective sense, so the connector is za.

That is why you get:

• sanaa za mitaani

rather than:

• sanaa ya mitaani

For an English speaker, the important thing to remember is that za here is not random—it is part of Swahili noun-class agreement.

Mitaani comes from mtaa, which can mean street, neighborhood, or district, depending on context.

The ending -ni is a locative ending, often giving the idea of in, at, or on a place.

So:

• mtaa = street / neighborhood
• mitaani = in the streets / on the streets / around the neighborhood streets

In this sentence, mitaani helps express the idea of street art.

Mjini comes from mji = town / city, plus the locative ending -ni.

So:

• mji = town / city
• mjini = in town / in the city

The difference is:

• mitaani = in/on the streets
• mjini = in town / in the city

So the sentence is talking about street art located in town.

They are related, but not identical.

• mitaani describes the kind or setting of the art: street art
• mjini gives the broader location: in town / in the city

So the sentence is not just saying art in town. It is saying street art in town.

Yes, to some extent. Swahili word order is flexible, though some orders sound more natural than others.

The original order is very natural:

• Kesho jioni, mimi na Juma tutaangalia sanaa za mitaani mjini.

This follows a common pattern:

time + subject + verb + object + place

You may hear variations for emphasis, but for learners, this sentence is a very good model to follow.
