Rahma aliuliza mzizi wa neno “kusoma” ni upi.

Because Swahili verbs normally carry a subject marker even when the subject noun is stated explicitly.

So in Rahma aliuliza:

• Rahma = the subject noun
• a- = subject marker for a singular person
• -li- = past tense
• -uliza = ask

That means Rahma aliuliza is the normal Swahili way to say Rahma asked.

Aliuliza can be broken down like this:

• a- = he/she
• -li- = past tense
• -uliz- = verb root meaning ask
• -a = final vowel

So aliuliza means he/she asked. Since Rahma is the subject, the whole beginning means Rahma asked.

Wa here means of, but more exactly it is the Swahili connective that links two nouns.

So:

• mzizi wa neno = the root of the word

The important point is that this connective agrees with the first noun, not the second one. Since mzizi belongs to the m-/mi- noun class in the singular, the connective appears as wa.

Compare:

• mzizi wa neno = root of the word
• mizizi ya maneno = roots of the words

Yes. Mzizi literally means root, and in grammar it can mean the root of a word.

In everyday learning materials, mzizi wa neno is a natural way to say word root. In more technical linguistics, people may sometimes distinguish between root and stem, but for most learners, mzizi here is simply root.

Because Swahili usually cites verbs in the infinitive form, which starts with ku-.

So:

• kusoma = to read / to study

That is the dictionary-style form of the verb. When someone asks for its root, they are asking what remains after removing the infinitive marker and other endings.

Depending on how technical the explanation is, a teacher might give:

• soma as the basic stem, or
• -som- as the root in a stricter grammatical analysis

So it is normal to mention the verb as kusoma, even in a sentence about its root.

Ni upi literally means something like is which one?

So the structure is:

• mzizi wa neno kusoma ni upi
  = the root of the word *kusoma is which one?*

In natural English, that becomes what is the root of the word *kusoma?*

The form upi agrees with mzizi, which is a singular noun in the m-/mi- class.

Both upi and gani can relate to English which, but they are used a little differently.

• upi often means which one?
• gani often directly modifies a noun, more like which ... ?

Here, ni upi is very natural because the sentence is identifying one specific answer: Which one is it?

So:

• mzizi ni upi? = which one is the root? / what is the root?

A form with gani would be structured differently, not usually this exact ni upi pattern.

Because Swahili does not always move question words to the front the way English does.

English says:

• What is the root of the word *kusoma?*

Swahili can keep the identifying question at the end:

• Mzizi wa neno kusoma ni upi?
• literally: The root of the word *kusoma is which one?*

That word order is normal in Swahili.

The direct question would be:

• Mzizi wa neno kusoma ni upi?

Then the full sentence simply reports that question:

• Rahma aliuliza mzizi wa neno kusoma ni upi.

So the sentence is an indirect question: Rahma asked what the root of the word *kusoma is.*

Not strictly, but they are helpful.

They show that kusoma is being mentioned as a word, not just used in the sentence. In grammar discussions, that is very common.

You might also see the word:

• in quotation marks
• in italics
• in bold

All of these help show that the speaker is talking about the word itself.
