Elektroni ni ndogo.

Ni is the usual Swahili word for is / are when you connect a subject to a description or identity.

So:

• Elektroni ni ndogo. = An/The electron is small or Electrons are small, depending on context.

In this sentence:

• Elektroni = the subject
• ni = is/are
• ndogo = small

A very common pattern in Swahili is:

• X ni Y = X is Y

For example:

• Jiji ni kubwa. = The city is big.
• Maji ni muhimu. = Water is important.

The basic adjective stem is -dogo, meaning small. In an actual sentence, Swahili adjectives usually take a class prefix that matches the noun.

Elektroni belongs to the N-class (also called class 9/10 in many grammar descriptions). With this class, -dogo becomes ndogo.

So:

• stem: -dogo
• with the noun class of elektroni: ndogo

This is called noun class agreement.

Elektroni is treated like a noun in the N-class (class 9/10), which contains many loanwords, animals, and other nouns whose singular and plural often look the same.

This matters because adjectives and some other words have to agree with the noun class.

That is why you get:

• elektroni ... ndogo

rather than some other adjective form.

For learners, the main practical point is:

• memorize the noun together with its agreement pattern
• notice that many borrowed scientific words in Swahili behave this way

It can be singular or plural, depending on context.

In Swahili, many nouns in this class have the same form in singular and plural, and elektroni is one of them.

So Elektroni ni ndogo could mean:

• The electron is small
• An electron is small
• Electrons are small

Context tells you which meaning is intended.

If you want to make plurality clearer, context usually does the job better than the noun form itself.

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

So elektroni by itself can mean:

• an electron
• the electron
• electrons

The exact meaning depends on context.

This is very normal in Swahili. You do not need to insert a separate word for the or a.

This is a very common pattern, yes.

In simple statements like this, Swahili often uses:

• subject + ni + description

So:

• Elektroni ni ndogo.
• Kitabu ni kizuri.
• Nyumba ni kubwa.

However, Swahili can also express descriptions in other ways, especially with full verbal constructions. But for a basic equational sentence like this, noun + ni + adjective is exactly what you should expect.

Normally, for a full standard sentence meaning The electron is small, you should keep ni:

• Elektroni ni ndogo.

If you say Elektroni ndogo, it does not sound like the normal full sentence in standard usage. It may sound incomplete, or more like a noun phrase such as a small electron, depending on context and style.

So for learners, the safe rule is:

• use ni when you mean is/are in this kind of sentence

Because the noun class of elektroni uses the same visible pattern here for both singular and plural.

With class 9/10 nouns:

• the noun often looks the same in singular and plural
• the adjective agreement may also look the same in both

So:

• elektroni ndogo can refer to a small electron or small electrons, depending on context

This is one reason Swahili relies heavily on context.

A simple learner-friendly pronunciation guide would be:

• Elektroni ≈ eh-lek-TROH-nee
• ni ≈ nee
• ndogo ≈ n-DOH-go

A few helpful points:

• Swahili vowels are usually pure and stable:
  • e as in bet but cleaner
  • i as in machine
  • o as in go but without a glide
• In ndogo, the n is pronounced together with the d at the start: nd-

Swahili spelling is fairly regular, so once you learn the sound system, pronunciation becomes much easier than in English.

Ndogo usually means small in a broad sense. It can describe physical size, but depending on context it can also suggest something like:

• small in amount
• young/younger
• minor

In Elektroni ni ndogo, the natural meaning is physical or scientific size: the electron is small.

So here ndogo is being used in the straightforward sense of small.

Yes, absolutely.

Because elektroni can be singular or plural, and because Swahili does not use articles the way English does, this sentence can naturally be interpreted as:

• An electron is small
• The electron is small
• Electrons are small

If this is a general scientific statement, Electrons are small is often the most natural English translation.

You can add sana, which means very or a lot:

• Elektroni ni ndogo sana.

That means:

• The electron is very small
• Electrons are very small

This is a very common way to strengthen an adjective in Swahili:

• kubwa sana = very big
• nzuri sana = very good
• ndogo sana = very small
