Wigo wa kazi uko wazi.

Wigo means scope, range, or extent.

In the phrase wigo wa kazi, it refers to the scope of work—the limits, coverage, or defined area of the work being discussed.

Wa is the connective word that often corresponds to of in English.

So:

• wigo wa kazi = scope of work

A useful thing to remember is that this connector agrees with the first noun (wigo), not the second one (kazi).

Swahili normally puts the main noun first and then adds the of phrase after it, so wigo wa kazi is the natural order.

Wigo behaves like a class 11 noun.

That matters because noun class controls agreement in Swahili. In this sentence, it affects:

• the connector: wa
• the predicate form: u- in uko

So the grammar of the sentence is built around the noun class of wigo, not around natural gender the way English sometimes works.

Here, uko is made up of:

• u- = the agreement marker matching wigo
• -ko = a copular/state element often used for location or condition

So uko wazi means something like is in an open/clear state.

This pattern is very common in Swahili with states or conditions, for example:

• Mlango uko wazi = The door is open.
• Chakula kiko tayari = The food is ready.

Also, you may already know uko as you are in some contexts. That is true, but not here. In this sentence, it is agreeing with wigo, not referring to you.

Because iko is used with different noun classes.

For example:

• nyumba iko wazi = the house is open

But wigo does not take that agreement pattern. Since wigo takes u- agreement here, the correct form is:

• wigo wa kazi uko wazi

So this is a noun-class agreement issue, not a meaning issue.

You may hear ni wazi in Swahili, especially with the sense of it is clear / it is obvious.

However, in a sentence like this, uko wazi is the more natural pattern for describing a current state or condition.

So for a learner, Wigo wa kazi uko wazi is the safer and more idiomatic choice.

Because wazi is usually treated as an invariable adjective/state word. It often stays the same even when the noun class changes.

For example:

• mlango uko wazi = the door is open
• milango iko wazi = the doors are open
• dirisha liko wazi = the window is open
• madirisha yako wazi = the windows are open

Notice that the agreement changes in uko / iko / liko / yako, but wazi stays wazi.

It can mean both, depending on context.

Common uses:

• open: a door, gate, shop, window
• clear / plain / explicit: instructions, rules, plans, scope

So in Wigo wa kazi uko wazi, wazi is likely understood as clear, well-defined, or explicit, though the core idea is still something like open / not closed off.

You can say:

Wigo wa kazi hauko wazi.

That means The scope of work is not clear/open.

Here, hauko is the negative form that matches the noun class of wigo.
