Tulipofika supermarketi mapema, tulinunua maziwa, sabuni na matunda mengi.

It breaks down as:

• tu- = we
• -li- = past tense
• -po- = when
• fika = arrive

So Tulipofika means when we arrived.

Swahili often packs information that English expresses with several words into a single verb form. That is very normal, especially with subject markers and tense markers.

Here -po- gives the idea of when in a time clause.

So:

• tulifika = we arrived
• tulipofika = when we arrived

This is a very common pattern in Swahili for saying when ..., especially in past-time narration.

It is:

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

So tulinunua means we bought.

Again, Swahili includes the subject inside the verb, so you do not need a separate word for we.

Because Swahili verbs usually show the subject inside the verb itself.

In this sentence:

• Tulipofika = we arrived
• Tulinunua = we bought

A separate pronoun like sisi can be added, but usually only for emphasis or contrast. In ordinary sentences, the subject prefix on the verb is enough.

With verbs of motion or arrival, Swahili can often use the place name directly without an extra preposition-like word.

So tulipofika supermarketi is a natural way to say when we arrived at the supermarket.

You could also hear forms such as kwenye supermarketi, depending on style and context, but the version in the sentence is perfectly normal.

It is a loanword from English supermarket, adapted to Swahili spelling and pronunciation.

That happens a lot in modern Swahili, especially with newer objects, technology, business terms, and international vocabulary.

The final -i is typical of how many borrowed words fit more naturally into Swahili sound patterns.

Mapema means early.

In this sentence it describes the time of arriving, so the idea is when we arrived at the supermarket early or more naturally when we got to the supermarket early.

Adverbs in Swahili are often fairly flexible, but this placement is natural. The important thing is that mapema is modifying the arrival, not the buying.

That is a very common learner question.

Maziwa is the normal Swahili word for milk, even though it has the shape of a plural noun. In everyday use, it is treated as a mass noun.

So you should usually just learn:

• maziwa = milk

This is one of those cases where English and Swahili do not match neatly. The singular-looking form ziwa does exist, but it usually means lake, not one milk.

In Swahili, adjectives normally come after the noun.

So:

• matunda mengi = many fruits

Not:

• mengi matunda

That word order is one of the first big differences English speakers notice.

Because adjectives in Swahili must agree with the noun class of the noun they describe.

Here:

• tunda = fruit
• matunda = fruits

Matunda is in noun class 6, so -ingi becomes mengi in agreement with that class.

So:

• matunda mengi = many fruits

This kind of agreement is a central feature of Swahili grammar.

Usually sabuni is the same in both singular and plural.

So depending on context, sabuni can mean:

• soap
• soaps

Many Swahili nouns, especially in certain noun classes and many loanwords, do not change form between singular and plural. You understand the number from context, adjectives, verbs, or the overall meaning of the sentence.

Swahili does not normally use articles like English a/an and the.

So a noun like maziwa can mean:

• milk
• the milk
• some milk

The exact meaning depends on context.

That is why the sentence can be perfectly complete without any separate words for the or some.

The comma separates the time clause from the main clause:

• Tulipofika supermarketi mapema = time/background
• tulinunua maziwa, sabuni na matunda mengi = main action

This is similar to English punctuation in sentences like When we arrived early at the supermarket, we bought milk, soap, and many fruits.

The comma is a writing choice that makes the sentence easier to read.
