Troli ile ilisimama karibu na mlango, kwa hiyo mama akairudisha mahali pake kabla hatujaondoka.

In Swahili, demonstratives normally come after the noun, not before it.

So:

• troli ile = that trolley
• not ile troli

Also, the demonstrative has to agree with the noun class. Troli is usually treated as a class 9 noun in the singular, so the matching demonstrative is ile.

Many borrowed nouns in Swahili do not show an obvious class prefix, but they still belong to a noun class for agreement purposes. Troli is commonly treated like a class 9/10 noun.

That is why you get:

• troli ile = that trolley
• troli ilisimama = the trolley stood/stopped

If it were plural, you would typically see class 10 agreement, for example:

• troli zile
• troli zilisimama

So the class is shown by the agreement words, not necessarily by the noun’s shape.

Ilisimama can be broken down as:

• i- = subject marker for it (class 9 singular)
• -li- = past tense
• simama = stand / stop

So i-li-simama literally means it stood or it stopped.

Swahili often puts the subject information inside the verb, so there is no separate word for it here.

It can mean either, depending on context.

Common uses of kusimama include:

• to stand
• to be standing
• to stop
• to come to a halt

With something like a trolley, the idea is usually that it was standing there or had stopped there. English may choose different words, but the Swahili verb covers both ideas.

Karibu na is a fixed expression meaning near or close to.

So:

• karibu na mlango = near the door

The na is part of the normal construction here. You should learn karibu na as a unit.

Also note that karibu by itself can mean different things in different contexts, such as:

• near
• welcome
• come in

But in this sentence, karibu na clearly means near.

Kwa hiyo is a connector meaning:

• so
• therefore
• for that reason

It links the first idea to the result:

• the trolley was near the door,
• so / therefore mother put it back.

Literally, kwa hiyo is something like because of that / by that, but in normal English it is best translated as so or therefore.

Swahili verbs often pack a lot of information into one word.

Akairudisha can be broken down like this:

• a- = she/he
• -ka- = consecutive/sequential marker, often meaning and then or so
• -i- = it (object marker for a class 9 noun, here referring to troli)
• rudisha = return something / put back / bring back

So a-ka-i-rudisha means something like:

• so she returned it
• and then she put it back

The -ka- is especially common in storytelling or connected events.

This is a very important distinction:

• kurudi = to return / go back / come back
• kurudisha = to return something / bring something back / put something back

So:

• nimerudi = I have returned / I came back
• nimerudisha kitabu = I returned the book

In this sentence, the mother is doing something to the trolley, so Swahili uses the transitive verb kurudisha, not kurudi.

Because mama refers to a person, it takes class 1 singular agreement, even though the word itself does not begin with m- in the usual way learners may expect.

So:

• mama a-na-kuja = mother is coming
• mama a-ka-i-rudisha = mother then returned it

In other words, agreement in Swahili depends on the noun class the word belongs to, not only on how the word looks.

Because mahali is a locative-type noun, and locative nouns often use locative agreement in possessives.

So:

• mahali pake = its/his/her place

Here, pake is built from a locative agreement element plus -ake.

A key point is that the possessive agrees with mahali, the noun being possessed, not directly with troli.

Also, Swahili does not have a special separate word for its the way English does. The ending -ake can mean his, her, or sometimes its, depending on context. In this sentence, context shows that it means the trolley’s proper place.

After kabla (before), Swahili very often uses a negative perfect form.

So:

• ha-tu-ja-ondoka
  • ha- = negative
  • tu- = we
  • -ja- = perfect in this negative pattern
  • ondoka = leave

This gives the idea of:

• before we had left
• before we left
• literally something like before we had not yet left

That may feel unusual to an English speaker, but it is a normal Swahili pattern.

Because Swahili usually puts the subject information inside the verb itself.

For example:

• a- in akairudisha = she/he
• tu in hatujaondoka = we

So separate pronouns are often unnecessary unless the speaker wants emphasis, contrast, or clarity.

That is why Swahili sentences can look very compact: one verb may already include the subject, tense, object, and more.
