Nikienda jikoni, ngoja sebuleni pamoja na bibi.

Nikienda comes from:

• ni- = I
• -ki- = a marker often meaning if, when, or while
• -enda = go

So nikienda literally means something like if/when I go or while I am going. In this sentence, the most natural English idea is usually when I go to the kitchen or if I go to the kitchen, depending on context.

This -ki- form is very common in Swahili for actions that happen in connection with another action.

This first part sets the situation for the main command.

• Nikienda jikoni = When/if I go to the kitchen
• ngoja sebuleni pamoja na bibi = wait in the living room with grandmother

So the structure is:

• background situation first
• main instruction second

This is very natural in Swahili. It works a lot like English clauses such as:

• When I leave, stay here.
• If I go inside, wait outside.

Ngoja here is a command: wait.

So it is the imperative form, used when telling someone to do something.

Compare:

• ngoja! = wait!
• ninangoja = I am waiting
• anangoja = he/she is waiting

In this sentence, the speaker is telling someone what to do, so ngoja is correct.

In Swahili, commands often do not include an explicit word for you. It is understood.

So:

• ngoja = wait (you, singular)

If the speaker wanted to address more than one person, a different form could be used, such as ngojeni = wait (you all).

So the sentence is speaking to one person, unless context suggests otherwise.

The -ni ending often marks a location in Swahili.

So:

• jikoni = in/to the kitchen
• sebuleni = in/to the living room

This is a very common pattern with place words. The exact English translation may be in, at, or to, depending on the verb and the context.

Here:

• nikienda jikoni = when/if I go to the kitchen
• ngoja sebuleni = wait in the living room

Pamoja na means together with or simply with.

So:

• pamoja na bibi = with grandmother

It emphasizes being together in company with someone.

In many situations, na alone can also mean with, but pamoja na gives a clearer sense of together with.

Bibi most often means:

• grandmother
• sometimes grandma
• sometimes an older woman or a respectful way to address a woman, depending on context

In a learning sentence like this, it usually means grandmother.

So pamoja na bibi is most likely with grandmother or with grandma.

All three can be possible, depending on context.

The -ki- form is broader than a single English word, so translation depends on the situation:

• if I go
• when I go
• while I go / while I’m going

In this sentence, the most natural English choices are probably:

• When I go to the kitchen, wait in the living room with Grandma.
• If I go to the kitchen, wait in the living room with Grandma.

So the Swahili form is a little flexible, and English has to choose the best fit.

Yes, it is understandable and natural.

Its structure is:

• Nikienda jikoni = dependent clause: when/if I go to the kitchen
• ngoja sebuleni pamoja na bibi = main clause: wait in the living room with grandmother

So the full pattern is:

• [When/if X happens], [do Y].

That is a very common and useful Swahili pattern.

Yes, the order could be changed, though the original is very natural.

For example, you could also say:

• Ngoja sebuleni pamoja na bibi nikienda jikoni.

That still gives the same basic idea, but the original version is usually clearer because it sets up the condition or situation first.

So:

• Nikienda jikoni, ngoja sebuleni pamoja na bibi.

is a good standard way to say it.

The comma separates the two parts:

• Nikienda jikoni = the introductory clause
• ngoja sebuleni pamoja na bibi = the main command

This is similar to English punctuation in sentences like:

• When I go to the kitchen, wait in the living room.

The comma helps the reader see the sentence structure more easily.
