Leo usiku, tutaangalia runinga pamoja.

Swahili often expresses tonight literally as today night:

• leo = today
• usiku = night

So leo usiku means tonight.

This is very natural in Swahili. You may also see:

• usiku wa leo = tonight, literally the night of today

Both are correct, though leo usiku is very common in everyday speech.

tutaangalia can be divided into:

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

So:

• tu-ta-angalia = we will watch

This is a very typical Swahili verb structure:
subject prefix + tense marker + verb stem

In Swahili, the subject is usually built into the verb itself.

So instead of saying a separate word for we, the verb already includes it:

• tu- = we

That means tutaangalia already tells you we will watch.

You could add sisi for emphasis:

• Sisi tutaangalia runinga pamoja. = We will watch TV together.

But in a normal sentence, sisi is not necessary.

The dictionary form is usually:

• kuangalia = to watch / to look at

Here:

• ku- = the infinitive marker, like to in English
• -angalia = the verb stem

When the verb is conjugated, the ku- disappears and other markers are added:

• kuangalia = to watch
• tutaangalia = we will watch

runinga usually means television or TV, and in this sentence it means TV in the everyday sense: watching television.

Depending on context, it can refer to:

• the television set
• television as a medium/programming

In everyday conversation, learners may also hear borrowed forms like televisheni, but runinga is a standard Swahili word.

Swahili does not use articles like a, an, and the the way English does.

So:

• runinga can mean TV, a television, or the television, depending on context.

In this sentence, the natural English translation uses TV, but Swahili does not need an article there.

pamoja means together.

Putting it at the end is very natural in Swahili:

• Leo usiku, tutaangalia runinga pamoja.

This is similar to English, where together often comes near the end:

• Tonight, we will watch TV together.

Swahili word order is somewhat flexible, but this placement sounds normal and clear.

Yes, sometimes it can, but the version in your sentence is the most natural and common.

For example:

• Leo usiku, pamoja tutaangalia runinga.

This is possible, but it may sound more marked or emphatic, as if stressing together.

For a learner, the safest pattern is:

• subject + verb + object + pamoja

So:

• tutaangalia runinga pamoja = we will watch TV together

Not always. -angalia has a broader meaning than English watch.

It can mean:

• look at
• watch
• observe
• sometimes check

Examples:

• Angalia hapa. = Look here.
• Ninaangalia runinga. = I am watching TV.

So in this sentence, tutaangalia runinga is understood as we will watch TV.

-ta- is the regular future marker, so tutaangalia means we will watch.

In many situations, English will watch and are going to watch are both possible translations, depending on context.

So tutaangalia can often match either of these English ideas:

• we will watch
• we are going to watch

But grammatically in Swahili, it is simply the future tense form.

A few helpful pronunciation notes:

• leo is pronounced roughly LEH-oh
• usiku is roughly oo-SEE-koo
• tutaangalia is roughly too-tah-ahn-gah-LEE-ah
• runinga is roughly roo-NEEN-gah
• pamoja is roughly pah-MOH-jah

A few general rules help:

• Swahili vowels are usually pronounced clearly and consistently.
• Most syllables are open, ending in a vowel.
• Stress is usually on the second-to-last syllable.

So:

• tu-ta-an-ga-LI-a
• pa-MO-ja
• ru-NIN-ga

Yes. -tazama can also mean watch or look at, so:

• Tutatazama runinga pamoja.

is also a valid sentence.

However, -angalia is extremely common for watching TV, so the original sentence sounds perfectly natural.

For learners, it is useful to know that several verbs may overlap in meaning:

• kuangalia = to watch / look at
• kutazama = to watch / look at / view

Swahili often puts time expressions near the beginning of the sentence, especially when setting the scene.

So:

• Leo usiku, tutaangalia runinga pamoja.

is very natural because it first tells you when, then what will happen.

You could move the time phrase later in some contexts, but the beginning position is common and clear. It works much like English:

• Tonight, we will watch TV together.
