Gari limejaa watu.

limejaa can be broken into three parts:

• li- = the subject marker for gari
• -me- = a perfect/result marker
• -jaa = be full

So limejaa literally gives the idea of it has become full or it is full.

In natural English, Gari limejaa watu is best understood as The car is full of people or The car is packed with people.

In Swahili, verbs usually agree with the noun class of the subject.

Here, gari takes the singular agreement marker li-, so:

• gari → li-
• Gari limejaa = The car is full

This is one of the noun-class agreement patterns that learners need to get used to. Even though gari is a loanword and does not visibly look like many other class nouns, its agreement here is li- in the singular.

The marker -me- often expresses a completed action with a present result.

So limejaa is not just about the filling happening in the past. It often means:

• it has filled up
• it is now full
• it has become full

That is why English often translates it simply as is full, even though the Swahili form contains -me-.

The dictionary form is kujaa, which means to be full or to fill up.

Examples:

• Gari limejaa. = The car is full.
• Chumba kimejaa. = The room is full.

When you add agreement and tense markers, kujaa changes shape:

• kujaa → infinitive
• limejaa → it is / has become full for gari

After kujaa, the thing that fills something often comes after the verb.

So:

• Gari limejaa watu.
• literally: The car has-filled people
• natural meaning: The car is full of people

In English, we need of: full of people.
In Swahili, that relationship is often expressed without a separate word like of in this kind of sentence.

Because with kujaa, Swahili commonly puts the thing that fills the space directly after the verb:

• limejaa watu = is full of people

Using na here is not the normal basic pattern for this sentence. A learner should remember:

• kujaa + noun
• kimejaa maji = it is full of water
• limejaa watu = it is full of people

So the most natural version is Gari limejaa watu.

Yes.

• mtu = person
• watu = people

So in this sentence, watu means people.

A useful pair to memorize is:

• mtu mmoja = one person
• watu wengi = many people

It can suggest that idea, but in normal use the main meaning is simply:

• The car is full of people
• The car has filled up with people
• The car is packed with people

So yes, there is a sense of a resulting state, but the most natural English translation is not usually the passive has been filled.

The basic order here is:

• Gari = subject
• limejaa = verb
• watu = complement showing what it is full of

So the pattern is roughly:

Subject + Verb + Noun

That is quite normal in Swahili.

Yes.

• Gari limejaa. = The car is full.

Adding watu tells you what the car is full of:

• Gari limejaa watu. = The car is full of people.

So the shorter sentence is grammatical, but less specific.

The normal plural is:

• Magari yamejaa watu.

Here the changes are:

• gari → magari = car / cars
• li- → ya- for plural agreement
• limejaa → yamejaa

So:

• Gari limejaa watu. = The car is full of people.
• Magari yamejaa watu. = The cars are full of people.

A simple pronunciation guide is:

• li-me-ja-a

Swahili is usually pronounced quite regularly, syllable by syllable.
The jaa part is often heard as two vowel beats: ja-a.

And the whole sentence can be sounded out like:

• ga-ri li-me-ja-a wa-tu

Every vowel is pronounced clearly.

Yes. It is a very natural way to describe a place or vehicle being crowded or full.

The same pattern is used with many nouns:

• Chumba kimejaa watu. = The room is full of people.
• Ndoo imejaa maji. = The bucket is full of water.
• Barabara imejaa magari. = The road is full of cars.

So this sentence teaches a very useful structure:

[thing] + [agreement + -me- + -jaa] + [what it is full of]
