Nitakukumbusha kuhusu mkutano kesho asubuhi.

It is made of several pieces:

• ni- = I
• -ta- = future marker, will
• -ku- = object marker, you (singular)
• -kumbusha = remind

So Swahili packs subject + tense + object + verb into one word.

Because the subject is already built into the verb.

In Nitakukumbusha, the ni- already means I.
So a separate pronoun like mimi is usually unnecessary unless you want emphasis:

• Mimi nitakukumbusha = I will remind you

That sounds more emphatic, like I’ll be the one to remind you.

A learner often notices ni-ta-ku-kumbusha and wonders about that.

The first -ku- is the object marker meaning you.
The next k is simply the beginning of the verb stem -kumbusha.

So this is not two separate words. It is just:

• ni-
  • -ta-
    • -ku-
      • -kumbusha

They are related, but not the same:

• kumbuka = remember
• kumbusha = remind

So:

• Ninakumbuka = I remember
• Nitakukumbusha = I will remind you

The -sha ending often gives a causative idea, so kumbusha is basically make someone remember.

Kuhusu means about, concerning, or regarding.

So kuhusu mkutano means about the meeting.

It links the action of reminding to the topic:

• Nitakukumbusha kuhusu mkutano = I will remind you about the meeting

Swahili normally does not use articles like English a/an/the.

So mkutano can mean:

• a meeting
• the meeting

The exact meaning depends on context.

If you want to be more specific, Swahili can use other words, such as demonstratives:

• mkutano huo = that meeting
• mkutano ule = that meeting over there / that specific meeting

Mkutano is a noun meaning meeting. Its plural is:

• mkutano = meeting
• mikutano = meetings

It belongs to the m-/mi- noun class.

You do not need to master all noun classes immediately, but it is useful to notice the singular/plural pattern:

• m- singular
• mi- plural

As written, kesho asubuhi most naturally describes when the reminding will happen.

So the sentence is most naturally understood as:

• I will remind you tomorrow morning about the meeting

If you want tomorrow morning to describe the meeting, Swahili often makes that clearer with wa:

• Nitakukumbusha kuhusu mkutano wa kesho asubuhi

That means I will remind you about tomorrow morning’s meeting or the meeting tomorrow morning.

Time expressions often come near the end of a Swahili sentence, especially after the main verb and other complements.

So this order is very natural:

• Nitakukumbusha kuhusu mkutano kesho asubuhi

But Swahili word order is somewhat flexible, and you can move the time phrase for emphasis:

• Kesho asubuhi nitakukumbusha kuhusu mkutano

That puts more focus on tomorrow morning.

Yes. The object marker changes depending on who is being reminded.

For example:

• Nitakukumbusha = I will remind you
• Nitamkumbusha = I will remind him/her
• Nitatukumbusha = I will remind us

This is a very common Swahili pattern: the verb includes the object inside it.

Swahili pronunciation is usually quite regular, and stress normally falls on the second-to-last syllable of each word.

A rough breakdown:

• Ni-ta-ku-kum-bu-sha
• ku-hu-su
• m-ku-ta-no
• ke-sho
• a-su-bu-hi

So the stressed parts are roughly:

• ni-ta-ku-kum-BU-sha
• ku-HU-su
• m-ku-TA-no
• KE-sho
• a-su-BU-hi

Also, vowels are usually pronounced clearly:

• a as in father
• e as in bed (but cleaner/purer)
• i as in machine
• o as in go (without a strong glide)
• u as in flute

Yes. It is a natural and correct sentence.

It sounds neutral and normal for everyday use. It is neither especially formal nor especially slangy.

A speaker might also choose slightly different wording depending on context, but this version is perfectly good standard Swahili.
