Tarehe ya ukomo wa mkataba wa bima ni kesho.

Tarehe means date. In this sentence, it refers to a specific calendar date, not just time in general.

So Tarehe ya ukomo wa mkataba wa bima means something like the expiration date of the insurance contract.

They link nouns together, a bit like of in English.

Here is the structure:

• tarehe ya ukomo = date of expiration / end date
• ukomo wa mkataba = expiration/end of the contract
• mkataba wa bima = insurance contract or literally contract of insurance

So Swahili often builds long noun phrases by chaining nouns together with linking words like ya and wa.

This is because these connectors agree with noun classes in Swahili.

• tarehe takes ya
• ukomo takes wa
• mkataba also takes wa

So the connector changes depending on the noun before it, not the noun after it.

That means:

• tarehe ya ...
• ukomo wa ...
• mkataba wa ...

This is very normal in Swahili grammar, even though it can feel unusual to English speakers.

Ukomo means limit, end point, termination, or expiry, depending on context.

In this sentence, it refers to the expiration or end of the contract. So tarehe ya ukomo is the expiry date or termination date.

A learner might also know mwisho, which means end more generally. Ukomo sounds a bit more formal and fits well in legal or official contexts like contracts.

Mkataba means contract or agreement.
Bima means insurance.

So mkataba wa bima means insurance contract.

Literally, it is contract of insurance. Swahili often uses this noun + wa + noun pattern where English might prefer an adjective-like noun before another noun.

Ni is the basic Swahili copula, like is/are in English.

So:

• Tarehe ya ukomo wa mkataba wa bima ni kesho.
• The expiration date of the insurance contract is tomorrow.

Without ni, the sentence would feel incomplete here because you are equating one thing with another:

• subject: Tarehe ya ukomo wa mkataba wa bima
• complement: kesho

In Swahili, words for time such as leo (today), kesho (tomorrow), and jana (yesterday) often appear by themselves, without a word like on or in.

So:

• ni kesho = is tomorrow

English needs tomorrow too without a preposition in this kind of sentence, so this part is actually fairly straightforward for English speakers.

The sentence follows a very common pattern:

• subject
• ni
• complement

So:

• Tarehe ya ukomo wa mkataba wa bima = subject
• ni = is
• kesho = tomorrow

A literal breakdown is:

• Tarehe = date
• ya = of
• ukomo = expiration/end
• wa = of
• mkataba = contract
• wa = of
• bima = insurance
• ni = is
• kesho = tomorrow

Yes. This sentence is grammatical and quite formal, but in everyday speech people might also say something like:

• Mkataba wa bima unaisha kesho. = The insurance contract expires tomorrow.
• Bima inaisha kesho. = The insurance expires tomorrow.

The original sentence focuses specifically on the date of expiration, while these alternatives focus on the contract/insurance itself ending.

A rough pronunciation guide is:

Tah-reh-heh yah oo-koh-moh wah m-kah-tah-bah wah bee-mah nee keh-shoh

A few helpful notes:

• r in tarehe is usually lightly tapped.
• sh in kesho sounds like the sh in shoe.
• Swahili vowels are usually clear and consistent:
  • a as in father
  • e as in bet but often a bit tenser
  • i as in machine
  • o as in go but pure
  • u as in rule

Swahili pronunciation is generally quite regular, so once you know the sounds, it is usually easy to read aloud.

You do not need to master all noun classes immediately, but they help a lot with phrases like this.

The most important thing to notice here is that the linking word changes:

• ya
• wa

Those are not random. They agree with the noun before them.

At an early stage, many learners simply memorize common chunks such as:

• tarehe ya
• mkataba wa
• bima
• ni kesho

That is a perfectly good way to start. Later, learning noun classes will make patterns like this much easier to understand and produce on your own.
