Katika sentensi “hiki ni kitabu kizuri”, “kizuri” ni kivumishi na “hiki” ni kiwakilishi.

Hiki is a demonstrative pronoun. It means this or this one for nouns in the same noun class as kitabu.

In hiki ni kitabu kizuri, hiki stands on its own, so it functions as a pronoun: this is...

Compare:

• hiki ni kitabu = this is a book
• kitabu hiki = this book

In the second example, hiki is attached to a noun that is actually stated, so it behaves more like a demonstrative modifier rather than a stand-alone pronoun.

Because Swahili adjectives usually agree with the noun class of the noun they describe.

The adjective stem is -zuri = good.
Since kitabu belongs to the ki-/vi- noun class, the adjective takes the matching singular prefix ki-:

• kitabu kizuri = good book

If the noun were plural, the adjective would also change:

• vitabu vizuri = good books

So kizuri is not a random form; it is the agreement form required by kitabu.

This is because of noun-class agreement, which is one of the most important features of Swahili grammar.

Kitabu is a singular noun in the ki-/vi- class. Words connected to it often show that class through matching forms:

• kitabu = book
• hiki = this (for that noun class)
• kizuri = good (agreeing with that noun class)

English does not do this very much, so it can feel unusual at first. In Swahili, however, this matching happens all the time.

Because in Swahili, adjectives usually come after the noun they describe.

So the normal order is:

• kitabu kizuri = literally book good

English usually says good book, with the adjective first. Swahili usually says book good, with the adjective after the noun.

Here, ni is the copula, the word that links the subject and what is being said about it. In this sentence, it works like English is.

So:

• hiki ni kitabu kizuri = this is a good book

A simple way to think of it is:

• hiki = this
• ni = is
• kitabu kizuri = a good book

Swahili usually does not use separate articles like English a, an, and the.

So kitabu kizuri can mean:

• a good book
• the good book

The exact meaning depends on context, not on a separate article word.

This is very normal in Swahili, so English speakers often need time to get used to the fact that the article is simply not expressed.

Yes. If you include the noun itself, you would normally say:

• kitabu hiki = this book

In that structure, hiki is no longer standing alone as a pronoun. Instead, it is directly modifying the noun.

So compare these:

• hiki ni kitabu kizuri = this is a good book
• kitabu hiki ni kizuri = this book is good

Both are correct, but they are structured differently.

You have to change all the words that agree with the noun class:

• hivi ni vitabu vizuri

Breakdown:

• hivi = these
• ni = are / is
• vitabu = books
• vizuri = good

Notice the pattern:

• singular: hiki ni kitabu kizuri
• plural: hivi ni vitabu vizuri

The agreement changes from ki- to vi-.

No. Swahili has different demonstrative forms depending on distance or context.

For the noun class of kitabu, common forms include:

• hiki = this (near the speaker)
• hicho = that (near the listener or previously mentioned)
• kile = that over there (farther away)

So you might see:

• kitabu hiki = this book
• kitabu hicho = that book
• kitabu kile = that book over there

All of these still agree with the noun class of kitabu.
