Mizigo ya mkononi iko katika chumba cha abiria.

In Swahili, mzigo is a normal countable noun meaning load, burden, or piece of baggage. Its plural is mizigo.

So where English often uses uncountable luggage, Swahili commonly uses the plural mizigo for baggage or bags in general.

• singular: mzigo
• plural: mizigo

At an airport, mizigo sounds completely natural.

Ya is a linking word often called the associative or genitive marker. It connects mizigo with the phrase that describes it.

So:

• mizigo ya mkononi = baggage of the hand → hand luggage / carry-on baggage

The form of this linker changes according to the noun class of the noun before it. Since mizigo belongs to the mi-/class 4 plural group, the correct linker is ya.

That is why it is:

• mizigo ya mkononi

not:

• mizigo za mkononi

Mkononi comes from:

• mkono = hand
• -ni = a locative ending meaning something like in, on, or at

So mkononi literally means in the hand or on the hand.

In this sentence, ya mkononi is an idiomatic way to say carried by hand, so the whole phrase means carry-on luggage or hand luggage.

Because mkononi is part of a fixed expression: ya mkononi = hand-held / carry-on.

The plurality is already shown by mizigo, and the linker ya agrees with mizigo. The word mkononi itself does not have to change to match the number of the luggage here.

So the natural expression is:

• mizigo ya mkononi

not normally:

• mizigo ya mikononi

Iko is used for location: it means is located, is found, or is there.

Swahili verbs agree with the noun class of the subject, not just with singular versus plural in the English way.

Here the subject is mizigo, which takes the subject agreement i- in this structure. With the locative stem -ko, you get:

• i + ko = iko

So:

• Mizigo ya mkononi iko... = The hand luggage is located...

Even though English might say is or are, Swahili uses noun-class agreement.

Because ni and iko do different jobs.

• ni is mainly for identifying or equating things: X is Y
• iko is for saying where something is: X is in/at Y

So:

• Mizigo ni chumba cha abiria would be wrong, because it would sound like The luggage is the passenger cabin
• Mizigo iko katika chumba cha abiria correctly means The luggage is in the passenger cabin

Katika means in, inside, or within.

So:

• iko katika chumba cha abiria = is in the passenger cabin

It is a very normal and slightly formal way to express location. In everyday speech, people might also say things like:

• iko kwenye chumba cha abiria
• iko ndani ya chumba cha abiria

But katika is perfectly correct and natural.

Literally, chumba cha abiria means room/cabin of passengers.

Breakdown:

• chumba = room, chamber, cabin
• cha = linking word that agrees with chumba
• abiria = passenger or passengers

So the phrase means the passenger cabin.

It is cha because chumba belongs to the noun class that uses cha as its linker. The linker agrees with chumba, not with abiria.

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

So:

• abiria can mean passenger
• abiria can also mean passengers

Context tells you which meaning is intended.

In chumba cha abiria, English usually translates it as passenger cabin or cabin for passengers.

Yes. The structure is very normal:

• Mizigo ya mkononi = subject
• iko = location verb
• katika chumba cha abiria = place/location phrase

So the sentence follows a common Swahili pattern:

• [thing] + [is located] + [place]

That makes the whole sentence feel straightforward and natural in Swahili.
