Swahili adjectives must always match the noun they describe.

This matching process is known as noun class agreement.

When you learn a new noun in Swahili, you also need to know its noun class.

The noun class tells you exactly which prefix to attach to the adjective.

I’ll explain exactly how this works with clear examples below.

Understanding Swahili noun prefixes

Nouns in Swahili are divided into different groups called classes.

Each class is identified by a specific prefix at the beginning of the word.

For example, words starting with m- and wa- usually refer to living things like people.

Words starting with ki- and vi- usually refer to inanimate objects.

You must know the prefix of the noun to use an adjective correctly.

How adjective agreement works

Adjectives in Swahili are made up of a root word called a stem.

You can’t use an adjective stem by itself.

You must attach a prefix to the stem so it matches the noun.

If the singular noun starts with m-, the adjective will usually start with m-.

If the noun starts with ki-, the adjective will also start with ki-.

Let’s look at the M/Wa (people) noun class using the adjective stem -zuri (good/beautiful).

Now let’s look at the Ki/Vi (objects) noun class using the exact same stem.

Notice how the adjective changes its beginning to mimic the noun.

Common Swahili adjective stems

Most native Swahili adjectives require you to add a prefix.

Here’s a list of the most common adjective stems you’ll use.

You can attach the correct noun prefix to any of these stems.

Invariable adjectives (the exceptions)

Not all adjectives in Swahili require a prefix.

Many Swahili words are borrowed from Arabic or English.

These loanwords are called invariable adjectives.

Invariable adjectives never change their form regardless of the noun class.

You simply place the word directly after the noun.

Here’s how you use them in a sentence without adding any prefixes.

Swahili adjective agreement is highly logical once you memorize your noun classes.

Always look at the beginning of the noun to figure out the adjective prefix.
