Kalenda mpya itaning'inizwa ukutani ofisini kesho asubuhi.

Yes:

• Kalenda = calendar
• mpya = new
• itaning'inizwa = it will be hung
• ukutani = on the wall / at the wall
• ofisini = in the office / at the office
• kesho asubuhi = tomorrow morning

A very literal order would be something like:

calendar new it-will-be-hung wall-at office-at tomorrow morning

So Swahili is expressing the same idea as English, but with different word order and noun/verb agreement.

Because the verb has to agree with kalenda.

Kalenda belongs to noun class 9 in the singular, and the subject marker for that class is i-. So:

• i- = it
• -ta- = will
• the rest of the verb = be hung

If you were talking about more than one calendar, the noun might still look the same, but the verb agreement would change:

• Kalenda mpya zitaning'inizwa... = The new calendars will be hung...

So the i- is not random; it is showing agreement with the subject noun.

Swahili adjectives also agree with the noun class of the noun they describe.

The adjective stem is -pya = new.
With a class 9 noun like kalenda, it becomes mpya.

So:

• kalenda mpya = new calendar

This agreement is very important in Swahili. Compare:

• kitabu kipya = new book
• nyumba mpya = new house
• kalenda mpya = new calendar

The adjective changes shape depending on the noun class.

It can be broken into parts like this:

• i- = subject marker, it
• -ta- = future tense, will
• -ning'iniza- = hang something
• -w- = passive, be ...ed
• -a = final vowel

So the basic idea is:

i-ta-ning'iniza-w-a
= it-will-hang-passive
= it will be hung

In practice, with a verb like -ning'iniza, the passive form appears as -ning'inizwa.

Because the sentence is focusing on the calendar, not on the person who will hang it.

English does the same thing:

• The new calendar will be hung...
  instead of
• Someone will hang the new calendar...

Swahili also uses the passive very naturally. If the doer is unknown, obvious, or not important, the passive is often preferred.

If you wanted to mention the doer, you could add it:

• Kalenda mpya itaning'inizwa na meneja...
  = The new calendar will be hung by the manager...

Here na means by in a passive sentence.

This is a very useful distinction.

• kuning'iniza = to hang something
• kuning'inia = to be hanging / to hang from something

So:

• Nitaning'iniza kalenda. = I will hang the calendar.
• Kalenda inaning'inia ukutani. = The calendar is hanging on the wall.

In your sentence, the passive of kuning'iniza is used:

• itaning'inizwa = it will be hung

That makes sense because the calendar is receiving the action.

The ending -ni is a locative ending. It often gives the sense of:

• in
• at
• on
• sometimes to

The exact English translation depends on context.

So:

• ukuta = wall
• ukutani = on the wall / at the wall

and

• ofisi = office
• ofisini = in the office / at the office

A helpful way to think of -ni is: it turns a noun into a location phrase.

Because they give two layers of location:

• ukutani = on the wall
• ofisini = in the office

Together, they mean:

on the wall in the office

So ukutani gives the more immediate location, and ofisini gives the larger place.

This kind of stacking is normal in Swahili. English uses extra prepositions, but Swahili can simply place the location words one after another.

Because Swahili does not normally use articles like English a, an, and the.

So kalenda mpya can mean:

• a new calendar
• the new calendar

The context tells you which one is intended.

In many real situations, a translation like the new calendar feels most natural because the speaker probably has a specific calendar in mind. But the Swahili itself does not explicitly mark the or a.

Yes. Swahili word order is somewhat flexible, especially with time expressions.

Your sentence ends with:

• kesho asubuhi = tomorrow morning

That is very natural. But you could also say:

• Kesho asubuhi kalenda mpya itaning'inizwa ukutani ofisini.

This also means The new calendar will be hung on the wall in the office tomorrow morning.

Putting the time phrase at the end is common, but moving it to the beginning can add emphasis to the time.

The important part is ng'.

In Swahili:

• ng' is pronounced like the ng in sing
• plain ng before a vowel often sounds more like the ngg in finger

So ning'inizwa has that sing-type sound in the middle, not a hard g sound there.

A rough pronunciation guide would be something like:

nee-ngi-nee-zwa

The last part -zwa is pronounced as one cluster: zwa.

You would need to name the person or people doing the action.

For example:

• Meneja ataning'iniza kalenda mpya ukutani ofisini kesho asubuhi.
  = The manager will hang the new calendar on the wall in the office tomorrow morning.

Compare the two:

• Kalenda mpya itaning'inizwa... = The new calendar will be hung...
• Meneja ataning'iniza kalenda mpya... = The manager will hang the new calendar...

So the passive version highlights the calendar, while the active version highlights the doer.
