Mkutano utaishia saa sita mchana.

The u- is the subject agreement prefix. It matches mkutano, which is a singular noun in noun class 3.

So the verb agrees with the noun:

• mkutano → u-
• mikutano → i-

For example:

• Mkutano utaishia... = The meeting will end...
• Mikutano itaishia... = The meetings will end...

A helpful way to break it down is:

• u- = subject marker for mkutano
• -ta- = future tense
• -ishia = the verb stem from kuishia

So utaishia means roughly it will end at / it will finish at.

Kuisha means to end or to finish.

Kuishia often means to end at, to end in, or to finish with, depending on context. The extra -ia gives the verb a more specific endpoint or relation.

In this sentence, kuishia connects the ending of the meeting to a particular time.

So:

• Mkutano utaisha = The meeting will end
• Mkutano utaishia saa sita mchana = The meeting will end at noon

Swahili does not always use prepositions in the same way English does. Time expressions often come directly after the verb.

Here, the idea of ending at a certain time is already built into the structure, especially with kuishia, so no extra word is needed before saa sita mchana.

This is a very common point of confusion for English speakers.

In traditional Swahili time-telling, counting starts from about 6:00 a.m., not from midnight. So:

• saa moja asubuhi = 7:00 a.m.
• saa sita mchana = 12:00 noon

So saa sita mchana means noon, not 6:00 p.m.

Mchana means daytime or afternoon/day period, and here it helps clarify the time.

This matters because saa sita could be unclear without context. For example:

• saa sita mchana = noon
• saa sita usiku = midnight

So mchana makes it clear that the sentence is talking about 12:00 in the daytime.

Yes. That is also natural and understandable.

• utaisha = will end
• utaishia = will end at / will finish at

Using utaishia makes the endpoint feel a little more explicit, but both versions can work in everyday Swahili.

Yes. The order is very natural:

• Mkutano = subject
• utaishia = verb
• saa sita mchana = time expression

So the pattern is basically:

Subject + verb + time

That is a very common and normal way to build a Swahili sentence.
