Wakiwa wamekula uduvi, watoto walitaka chai nyingine yenye iliki.

Wakiwa comes from wa-ki-wa:

• wa- = they (for people, noun class 2)
• -ki- = a marker often meaning when, while, or sometimes if
• -wa = be

So wakiwa literally means something like while they are / being.

In this sentence, it introduces a background clause: Wakiwa wamekula uduvi = after they had eaten shrimp / having eaten shrimp.

This is a very natural thing to notice.

The two forms work together:

• wakiwa = while/when they are being
• wamekula = they have eaten

Together, they mean being in the state of having eaten. In natural English, that usually becomes:

• after they had eaten shrimp
• once they had eaten shrimp
• having eaten shrimp

So the idea is not just while eating, but after the eating was already completed.

Compare:

• wakiwa wanakula = while they are eating
• wakiwa wamekula = after they have eaten / having eaten

Wamekula breaks down as:

• wa- = they
• -me- = perfect marker, often have
• -kula = eat

So literally it means they have eaten.

In this sentence, because it is inside the background clause, English often shifts it to had eaten rather than have eaten.

Because both forms refer to the same subject: watoto (children).

Watoto is a plural noun for people, so Swahili uses the class 2 subject marker wa-.

That is why you see:

• wakiwa = they being
• wamekula = they have eaten
• walitaka = they wanted

All three agree with watoto.

Swahili does not have articles like English the or a/an.

So watoto can mean:

• children
• the children
• sometimes even some children

The exact meaning depends on context.

In a full sentence like this one, English often needs an article, so watoto walitaka... is commonly translated as the children wanted...

In practice, uduvi often works like a collective or mass noun meaning shrimp or prawns in general.

So in English, depending on context, you might translate it as:

• shrimp
• prawns
• sometimes some shrimp

You do not need to force it into a strict English-style singular/plural interpretation every time. Here it simply tells you what they ate.

Walitaka breaks down as:

• wa- = they
• -li- = past tense marker
• -taka = want

So walitaka means they wanted.

This is a straightforward past-tense verb.

The adjective -ingine means other or another, but in Swahili adjectives must agree with the noun class.

Chai belongs to the N-class (class 9/10), so -ingine becomes nyingine.

So:

• chai nyingine = another tea / more tea

This agreement is why you do not just say chai ingine here.

It can cover more than one English idea, depending on context.

Most often in a sentence like this, it would naturally be understood as:

• another tea
• more tea
• in idiomatic English, often another cup of tea

Swahili often leaves things like cup unstated when the meaning is obvious from context. So chai nyingine does not have to explicitly mention kikombe (cup) to imply another serving.

Yenye means that has, having, or with, and it agrees with chai.

So:

• chai yenye iliki = tea with cardamom
• more literally: tea that has cardamom

And iliki means cardamom.

This phrase describes what kind of tea they wanted.

Because yenye is a neat way to describe something by what it contains.

• chai yenye iliki = tea containing cardamom / tea with cardamom

If you used na, the meaning might still be understandable, but yenye is better for having/containing as a characteristic of the tea.

It works a bit like a descriptive relative phrase:

• yenye = that has

So the tea is being defined as the tea that has cardamom in it.

The sentence has two parts:

1. Wakiwa wamekula uduvi
   = a background clause: after they had eaten shrimp

2. watoto walitaka chai nyingine yenye iliki
   = the main clause: the children wanted another cardamom tea / more tea with cardamom

So the full structure is:

• [background situation], [main action]

This is very common in Swahili: a dependent clause comes first, then the main clause.

Not in natural English.

Even though -ki- often has a while/when sense, the presence of wamekula shows that the eating is already completed. So the best English ideas are:

• after they had eaten shrimp
• once they had eaten shrimp
• having eaten shrimp

English while they had eaten sounds unnatural, so it is better not to translate it that way.
