Jibu ni sifuri.

Ni is the linking word that means is / are / am in this kind of sentence.

So Jibu ni sifuri has the structure:

• jibu = the answer
• ni = is
• sifuri = zero

A useful thing to know is that ni does not change for person or number the way English am / is / are does.

For example:

• Hili ni jibu. = This is an answer.
• Haya ni majibu. = These are answers.

Here, jibu is a noun meaning answer.

That can confuse learners because jibu! can also be the imperative verb answer!

Why is it a noun in this sentence? Because of its position and the structure:

• Jibu ni sifuri. = The answer is zero.

A command like Jibu! would usually stand alone or be followed by an object/context showing it is an instruction.

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

So jibu can mean:

• an answer
• the answer

The exact meaning depends on context. In your sentence, English naturally translates it as the answer because the context probably already makes clear which answer is meant.

Jibu belongs to noun class 5 in the singular. Its plural is majibu, which is class 6.

So:

• jibu = answer
• majibu = answers

This is worth learning because Swahili nouns belong to classes, and those classes affect agreement elsewhere in the sentence.

Example:

• Jibu moja = one answer
• Majibu mawili = two answers

Yes. Sifuri is the standard Swahili word for zero.

It is very commonly used in mathematics, scores, and everyday counting contexts.

You may sometimes also hear zero, especially in informal speech or where English has influence, but sifuri is the standard form learners should know.

In Jibu ni sifuri, sifuri is the predicate after ni, so it stays as sifuri.

English speakers sometimes expect lots of agreement everywhere, but here the key grammatical relationship is simply:

• subject: jibu
• linker: ni
• complement: sifuri

So there is no special change needed on sifuri in this sentence.

Yes. This is a very normal and straightforward Swahili sentence pattern:

subject + ni + complement

So:

• Jibu = subject
• ni = linking word
• sifuri = complement

This is the natural way to say The answer is zero.

A simple approximate pronunciation is:

JEE-boo nee see-FOO-ree

A few pronunciation tips:

• ji sounds like jee
• bu sounds like boo
• ni sounds like nee
• si sounds like see
• fu sounds like foo
• ri sounds like ree

Also, Swahili vowels are usually very consistent:

• a = ah
• e = eh
• i = ee
• o = oh
• u = oo

Yes. In a sentence like Jibu ni sifuri, English is is the most natural translation, but the meaning can also feel a bit like equals, especially in a math or test-answer context.

So depending on context, the sentence can feel like:

• The answer is zero
• The answer equals zero

Swahili still uses ni for that basic linking idea.
