Nitakujulisha baada ya kazi.

It can be divided into these parts:

• ni- = I
• -ta- = future tense marker, will
• -ku- = you (object marker, singular)
• -julisha = inform / let know

So Nitakujulisha literally means I will inform you or I will let you know.

In Swahili, object pronouns are often built directly into the verb.

So instead of saying something like I will inform you with a separate word for you, Swahili commonly uses:

• Ni-ta-ku-julisha
• I-will-you-inform

This is very normal in Swahili grammar. The object marker -ku- tells you who is being informed.

-julisha means to inform, to notify, or to let someone know.

It is related to the idea of knowledge and making someone know something. In everyday English, let you know is often the most natural translation.

So:

• Nitakujulisha = I’ll let you know
• Nitakujulisha baadaye = I’ll let you know later

Baada ya means after.

It is a fixed expression:

• baada = after / afterward
• ya = a linking word often translated loosely as of

So baada ya kazi is literally something like after work.

You should learn baada ya as a set phrase, because it is very commonly used:

• baada ya shule = after school
• baada ya chakula = after the meal / after food
• baada ya hapo = after that

Swahili does not use the or a/an the way English does.

So kazi can mean:

• work
• the work
• job
• sometimes duty/task, depending on context

In this sentence, baada ya kazi naturally means after work.

The exact sense comes from context, not from an article.

Yes. This word order is very natural.

It is:

• Nitakujulisha = I will let you know
• baada ya kazi = after work

So the structure is basically:

• Verb + time expression

This is very common in Swahili. You could sometimes move things around for emphasis, but this version is straightforward and idiomatic.

A helpful rough pronunciation is:

nee-tah-koo-joo-LEE-sha

A few tips:

• ni sounds like nee
• ta sounds like tah
• ku sounds like koo
• ju sounds like joo
• li sounds like lee
• sha sounds like shah

Swahili pronunciation is usually very regular, and each vowel is pronounced clearly.

Not always in the broadest sense, but in this kind of sentence it commonly means you as a singular object.

For example:

• Nitakuona = I will see you
• Nitakusaidia = I will help you
• Nitakupigia simu = I will call you

If you want to address more than one person, Swahili may use different strategies, and context matters. But for a learner, it is very useful to recognize -ku- as a very common marker for you.

Yes, depending on context, it could be understood in a few closely related ways:

• after work
• after the work
• after the job/task

In everyday conversation, people will usually understand it from the situation. If someone is talking about their daily routine, baada ya kazi most naturally means after work.

Yes, but it means something different.

• Nitakujulisha = I will inform you
• Nitajulisha = I will inform / I will make it known

Without -ku-, the sentence no longer specifically says you. The listener may still guess who is meant from context, but the object is not stated inside the verb.

So if you specifically want to say I’ll let you know, Nitakujulisha is the better form.

It is neutral and very usable in everyday speech.

Nitakujulisha baada ya kazi works well in many contexts:

• to a friend
• to a coworker
• in a practical everyday conversation

If you need to be more formal, you might choose different vocabulary depending on the situation, but this sentence itself is perfectly normal and polite enough in many cases.
