Tutakaa katika chumba cha abiria maadamu ni salama.

Tutakaa breaks down like this:

• tu- = we
• -ta- = future tense marker, will
• kaa = the verb stem stay, remain, sit, or sometimes live

So tutakaa means we will stay / we will remain in this sentence.

Here it most naturally means stay or remain.

The verb kaa can have several related meanings depending on context:

• sit
• stay
• remain
• sometimes live/reside

In Tutakaa katika chumba cha abiria..., the idea is not really we will sit in the passenger cabin, but rather we will stay/remain in the passenger cabin.

Yes, you often could.

Katika means in, inside, or within. It is a perfectly normal choice here and can sound a bit more neutral or formal.

Other common options are:

• kwenye = in/on/at, very common in everyday speech
• ndani ya = inside of, with a stronger sense of being physically inside

So these are all possible, with slightly different feel:

• katika chumba cha abiria
• kwenye chumba cha abiria
• ndani ya chumba cha abiria

In this sentence, katika is simply a standard way to say in the passenger cabin/room.

Literally, chumba cha abiria is something like room of passenger(s).

The word cha is a connector often called the associative or genitive marker. It links two nouns, and it changes form to match the first noun.

Here:

• chumba = room / cabin / compartment
• cha = the linker that agrees with chumba
• abiria = passenger / passengers

So chumba cha abiria means the passenger room/cabin, or more naturally the passenger cabin or passenger compartment.

If the first noun changed, the linker would change too. For example:

• chumba cha abiria = passenger room/cabin
• vyumba vya abiria = passenger rooms/cabins

It can be either singular or plural, depending on context.

Abiria is one of those Swahili nouns that often has the same form in both singular and plural:

• abiria mmoja = one passenger
• abiria wawili = two passengers

In chumba cha abiria, it is best understood generically, like passenger cabin or cabin for passengers. You do not need to force a singular/plural distinction in English.

Maadamu means as long as, so long as, or provided that.

It introduces a condition. In this sentence, it means:

• we will stay in the passenger cabin, provided that it is safe

So it is not mainly about length of time; it is about a condition being met.

Near-equivalents include:

• mradi
• ilimradi

All of these can mean something like provided that.

This is a very common thing for learners to notice.

Ni salama literally means it is safe or it’s safe, but Swahili often leaves this kind of subject implicit when it is obvious from context.

So maadamu ni salama means:

• as long as it is safe
• provided it is safe

The implied subject could be understood as the situation, staying there, or simply it in a general sense, just like English it is safe.

Swahili does not always spell out that kind of subject as explicitly as English does.

Yes.

You can say:

• Tutakaa katika chumba cha abiria maadamu ni salama.
• Maadamu ni salama, tutakaa katika chumba cha abiria.

Both are acceptable. The difference is mostly one of emphasis and style.

Putting maadamu ni salama first highlights the condition first, much like English:

• As long as it’s safe, we’ll stay in the passenger cabin.

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

So:

• chumba can mean a room, the room, or just room
• abiria can mean a passenger, the passenger, or passengers, depending on context

Definiteness is usually understood from the situation, or shown in other ways, such as with demonstratives:

• chumba hiki = this room
• chumba kile = that room

So the lack of the in chumba cha abiria is completely normal.

It can be more specific.

While chumba often means room, in context it can also mean:

• cabin
• compartment
• chamber

So in a transport-related sentence, chumba cha abiria is often better translated as passenger cabin or passenger compartment rather than just passenger room.

This is a good example of how the most natural English translation depends on context, even when the Swahili words are simple.
