Orodha ya walioitwa iko mtandaoni.

Orodha means list.

Swahili does not normally use articles like the or a/an, so orodha can mean:

• a list
• the list

Which one is meant depends on context. In this sentence, it is most naturally understood as the list.

Ya is a linking word often translated as of.

So:

• orodha ya... = list of...

It agrees with the noun that comes before it. Since orodha belongs to noun class 9, the connector is ya.

Compare:

• kitabu cha mwanafunzi = the student’s book / the book of the student
• orodha ya walioitwa = the list of those who were called

Walioitwa means those who were called or those who were invited/summoned.

Depending on context, it can also be understood more naturally in English as:

• those selected
• those admitted
• those shortlisted
• those who were named/called up

A lot depends on the situation. For example, in school or job contexts, walioitwa often refers to people who have been selected.

It can be broken down like this:

• wa- = plural marker for people
• -li- = past tense
• -o- = relative marker, giving the meaning who
• -itwa = be called, the passive form of -ita

So walioitwa literally means something like:

• they who were called

or more naturally:

• those who were called

This is a very common Swahili way of making expressions like the people who...

Because -ita means to call someone, while -itwa means to be called.

So:

• aliita = he/she called
• aliitwa = he/she was called

In walioitwa, the people are receiving the action, so the passive form is needed.

Iko means it is there, it exists, or it is located.

In this sentence, the most natural translation is:

• is online
• is available online

It comes from a locational form of the verb meaning to be in a place / to be situated.

So:

• Orodha ... iko mtandaoni = The list ... is online

Because ni is usually used to identify or equate things, like X is Y.

For example:

• Huyu ni mwalimu = This is a teacher
• Juma ni daktari = Juma is a doctor

But in your sentence, the idea is about location/state: the list is online. For that, Swahili uses a locational form such as iko.

So:

• ni = identity/classification
• iko = location/presence

Because orodha belongs to noun class 9, and the agreement prefix for that class here is i-.

So the verb agrees with orodha:

• orodha ... iko

If the noun belonged to another class, the form would change. For example:

• kitabu kiko mezani = the book is on the table
• vitabu viko mezani = the books are on the table

Agreement is a major feature of Swahili grammar.

Mtandaoni means online or on the internet.

It comes from:

• mtandao = network, often internet
• -ni = a locative ending, often meaning in/on/at

So mtandaoni literally suggests something like:

• on the network
• on the internet

In natural English, online is the best translation.

Not always. That is the most direct grammatical translation, but in real-life use it may sound more natural in English as something else.

Depending on context, walioitwa could mean:

• those selected
• successful applicants
• those admitted
• those invited
• the shortlisted candidates

So if this sentence appeared on a school, university, or employer website, it might idiomatically mean:

• The list of selected applicants is online
• The list of admitted students is online

Because Swahili often builds relative clauses directly into the verb.

In English, we say:

• those who were called

In Swahili, the who idea is included in the verb form itself through the relative marker -o-:

• wali-o-itwa

So instead of using a separate word like who, Swahili packs that meaning into the verb.

Yes. A very literal translation is:

• The list of those who were called is online.

But more natural English, depending on context, might be:

• The list of selected candidates is online.
• The list of admitted students is online.
• The list of successful applicants is online.
• The list is available online.

The best choice depends on what kind of list this is.
