Wakiwa wamekata tango na tikitimaji, watoto walipeleka sinia mezani.

Wakiwa is a form of kuwa, meaning to be. Here it introduces a background or circumstance clause.

In this sentence, wakiwa does not stand alone. It works with wamekata to give a meaning like:

• when they had cut
• after they had cut
• once they had finished cutting

So it helps set the scene before the main action.

This is a common Swahili pattern.

• wakiwa sets up the circumstance
• wamekata tells you the action of cutting is already completed

So wakiwa wamekata is not best translated word for word. As a whole, it means something like after they had cut or once they had cut.

English often uses a different structure, but Swahili is comfortable using this kind of being + already done pattern.

Wamekata can be broken down like this:

• wa- = they
• -me- = perfect aspect
• -kata = cut

So wamekata means they have cut or, in a past-story context like this one, they had cut or they were done cutting.

The important part is -me-, which shows the action is complete.

Walipeleka breaks down like this:

• wa- = they
• -li- = past tense
• -peleka = take / carry / bring to a place

So walipeleka means they took or they carried.

This is the main action of the sentence.

No. In walipeleka, -li- is the past tense marker, not an object marker.

So the structure is:

• wa- = subject marker, they
• -li- = past
• -peleka = verb root

A learner might notice that some noun classes also use forms that look similar, but here -li- is definitely just marking past tense.

Because in Swahili, each verb or verb-like form normally shows its own subject agreement.

The subject here is watoto, which is a plural human noun, so it takes class 2 agreement: wa-.

That is why you see:

• wakiwa
• wamekata
• walipeleka

This repetition is normal in Swahili and does not sound redundant.

Because Swahili can use both:

• the subject marker on the verb
• the full noun

The verb already tells you they, but watoto makes it explicit who they are.

Including watoto can add:

• clarity
• emphasis
• smoother style

If the context already made the subject obvious, Swahili could leave watoto out.

Meza means table.
When you add -ni, you get a locative form: mezani.

Depending on context, mezani can mean:

• at the table
• on the table
• to the table

Here, because the verb is walipeleka meaning they took/carried, the most natural meaning is to the table.

Not usually.

Because of -me- in wamekata, the cutting is viewed as already completed. So the idea is more like:

• after they had cut
• once they had cut

If you want while they were cutting, you would use a different structure, such as:

• wakikata
• walipokuwa wanakata

So this sentence is about a completed action before the next one happened.

Yes. That would be very natural.

For example:

Baada ya kukata tango na tikitimaji, watoto walipeleka sinia mezani.

That means roughly the same thing: After cutting cucumber and watermelon, the children took the tray to the table.

The difference is mainly nuance:

• baada ya kukata is a straightforward after doing X
• wakiwa wamekata slightly emphasizes the state of having already finished the cutting

Swahili usually does not have separate words that work exactly like English a, an, and the.

So words like:

• tango
• tikitimaji
• sinia
• watoto

do not need articles in Swahili.

English translations add a, the, or no article at all depending on context. That is why the meaning in English may look more specific than the Swahili words themselves.

Here na simply means and.

It joins the two nouns:

• tango
• tikitimaji

So tango na tikitimaji means cucumber and watermelon.
