Tukiwa na muda kesho jioni, tutasoma kitabu pamoja.

Tukiwa comes from the verb kuwa (to be).

It breaks down like this:

• tu- = we
• -ki- = a marker often used for if/when
• -wa = the verb stem from kuwa

So tukiwa literally means something like if/when we are.

In this sentence, it is followed by na muda (with time), so tukiwa na muda means if/when we have time.

In Swahili, the idea of if is often built into the verb itself, instead of being a separate word.

Here, the -ki- inside tukiwa carries the sense of if or when.

So instead of saying something like if we are with time, Swahili naturally says:

• tukiwa na muda = if/when we have time

This is a very common pattern in Swahili.

Yes—na commonly means and or with, but Swahili also uses kuwa na literally to be with to express to have.

So:

• kuwa na muda = literally to be with time
• natural English meaning: to have time

This is how possession is often expressed in Swahili:

• Nina kitabu. = I have a book.
• Tuna pesa. = We have money.

So in your sentence, tukiwa na muda is literally if we are with time, but naturally it means if we have time.

Kesho means tomorrow and jioni means evening.

So:

• kesho jioni = tomorrow evening

Swahili often places time expressions fairly freely, and this placement is completely natural.

Tutasoma comes from the verb kusoma (to read, or sometimes to study, depending on context).

It breaks down like this:

• tu- = we
• -ta- = future tense marker
• -soma = read/study

So:

• tutasoma = we will read / we will study

In this sentence, because the object is kitabu (book), the meaning is clearly we will read a book / the book.

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

So kitabu can mean:

• a book
• the book
• sometimes just book, depending on context

You figure out which meaning is intended from the situation or from the rest of the sentence.

So tutasoma kitabu pamoja could be understood as:

• we will read a book together
• we will read the book together

depending on context.

Kitabu belongs to the ki-/vi- noun class.

Its singular-plural pair is:

• kitabu = book
• vitabu = books

This matters because in Swahili, noun classes affect agreement in other parts of the sentence, especially adjectives, pronouns, and some verb-related forms.

For a beginner, the main thing to remember here is the pair:

• ki- singular
• vi- plural

So:

• kitabu kimoja = one book
• vitabu viwili = two books

Pamoja means together.

In this sentence:

• tutasoma kitabu pamoja = we will read a book together

It often comes near the end of the sentence, especially when it describes how an action is done.

Other examples:

• Tutaenda pamoja. = We will go together.
• Walifanya kazi pamoja. = They worked together.

It can be understood as either if or when, depending on context.

The -ki- form often covers both ideas:

• if the condition is uncertain
• when the condition is expected or general

So tukiwa na muda kesho jioni, tutasoma kitabu pamoja could sound like:

• If we have time tomorrow evening, we’ll read together
• or When we have time tomorrow evening, we’ll read together

In many cases, English forces you to choose one, but Swahili leaves it a bit more flexible.

Yes, you could say kama tuna muda, and it would also mean if we have time.

But there is a small difference in feel:

• tukiwa na muda sounds compact and very natural in connected speech
• kama tuna muda is also clear, but a bit more explicitly like if we have time

Both are correct, but the -ki- structure is extremely common in Swahili and is worth getting used to.

Yes, Swahili word order has some flexibility, especially with time expressions.

Your sentence is natural as:

• Tukiwa na muda kesho jioni, tutasoma kitabu pamoja.

You may also hear things like:

• Kesho jioni, tukiwa na muda, tutasoma kitabu pamoja.

Both are fine. The difference is mostly about emphasis:

• starting with kesho jioni emphasizes the time
• starting with tukiwa na muda emphasizes the condition

Not always. Kusoma can mean to read, but it can also mean to study in many contexts.

For example:

• Ninasoma kitabu. = I am reading a book.
• Ninasoma shule/chuoni. = I am studying at school/college.

In your sentence, because the object is kitabu, the meaning is clearly read:

• tutasoma kitabu = we will read a book

In standard Swahili, tu- means we, and there is no built-in inclusive/exclusive distinction like we including you versus we excluding you.

So:

• tukiwa = if/when we are
• tutasoma = we will read

If you need to make it clear whether the listener is included, you usually do that through context, not through a special verb form.
