Leo sokoni tulinunua biringanya na bamia kwa ajili ya chakula cha jioni.

It breaks down like this:

• tu- = we
• -li- = past tense
• -nunua = buy

So tulinunua means we bought.

This is a very common Swahili pattern:
subject marker + tense marker + verb stem

In this sentence, there is no object marker inside the verb because the things bought are named separately afterward: biringanya na bamia.

Because the tu- in tulinunua already tells you the subject is we.

Swahili usually does not need a separate subject pronoun unless you want emphasis or contrast. So:

• Tulinunua = we bought
• Sisi tulinunua = we bought / it was we who bought

The version without sisi is the normal, neutral one.

Sokoni comes from soko = market, plus the locative ending -ni.

So:

• soko = market
• sokoni = at the market / in the market / to the market

The exact English preposition depends on context. In this sentence, it most naturally means at the market.

This -ni ending is very common with places in Swahili.

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

So Leo at the start means something like:

• As for today...
• Today...

That is very natural Swahili word order. It tells the listener the time frame first, before the main action.

No, Swahili word order is fairly flexible.

This sentence uses a very natural order:

• Leo = time
• sokoni = place
• tulinunua = verb
• biringanya na bamia = objects
• kwa ajili ya chakula cha jioni = purpose

But other orders are possible, depending on what you want to emphasize. For example, you could move leo or sokoni later and still be understood.

So the word order here is natural, but not the only possible one.

Here, na means and.

So:

• biringanya na bamia = eggplants and okra

A useful thing to know is that na can also mean with, depending on context. But in this sentence, it is clearly just joining two nouns, so it means and.

Kwa ajili ya means for, for the sake of, or for the purpose of.

In this sentence, it explains why the vegetables were bought:

• kwa ajili ya chakula cha jioni = for dinner / for the evening meal

It is a longer, more explicit way to express purpose. Learners often first learn simple kwa = for, but kwa ajili ya is very common when you want to mean intended for or meant for.

Because cha is the associative marker that agrees with chakula.

This structure is very common in Swahili:

• noun + associative marker + noun

Here:

• chakula = food / meal
• cha = of for the noun class of chakula
• jioni = evening

So chakula cha jioni is literally food of the evening, which idiomatically means dinner or evening meal.

The important point is that the connecting word changes to match the noun class of the first noun. That is why you get cha here.

Yes, absolutely.

Even though it is literally built as food of evening, learners should recognize it as a normal expression for:

• dinner
• evening meal

So it is helpful to understand both levels:

• literal structure: meal of the evening
• natural meaning: dinner

Because Swahili does not use articles the way English does.

English often requires words like:

• the
• a
• an
• some

Swahili usually does not. Nouns can stand on their own, and the listener gets the meaning from context.

So biringanya na bamia can naturally mean something like:

• eggplants and okra
• the eggplants and the okra
• some eggplants and okra

The exact English choice depends on the situation, not on a separate Swahili article.

Not as strongly as English often does.

In real Swahili usage, especially with foods and market items, the sentence can leave the exact quantity to context unless it matters. If the speaker wanted to be very specific, they could add a number or another quantity expression.

So here the focus is not on the exact amount, but on the action and purpose: they bought biringanya and bamia for dinner.

Yes. A common alternative is a phrase like kwenye soko.

So both of these can refer to being at the market:

• sokoni
• kwenye soko

The -ni form is compact and very common, while kwenye soko is a more analytic phrasing. Learners should get comfortable with both patterns.
