-zuri

The adjective -zuri is one of the most common words in Swahili. It describes physical beauty, aesthetic appeal, and general quality, and it is also commonly used to describe a person's character (such as a 'nice' or 'good' person).

Here are the most important rules to remember when using it:

• Word Order: Adjectives Follow Nouns in Swahili. You will say mtoto mzuri (child good), not mzuri mtoto.
• Agreement: The prefix must match the noun class. For people (Class 1/2), use m- and wa- (mtoto mzuri, watoto wazuri). For Class 7/8, use ki- and vi- (kitabu kizuri, vitabu vizuri).
• Animate Nouns: For descriptive adjectives like -zuri, all animate nouns (animals and people) take Class 1/2 adjective prefixes (m- and wa-), regardless of what noun class they actually belong to. For example, you say mbwa mzuri (a good dog) and rafiki mzuri (a good friend), not mbwa nzuri.
• Class 3/4 (M-MI Class): For trees, plants, and other Class 3/4 nouns, use the prefixes m- and mi- (mti mzuri for a good tree, miti mizuri for good trees).
• The Class 5/6 Exception: For Class 5 nouns (like gari or tunda), multi-syllable adjectives starting with a consonant take a zero-prefix. This means you just use the root: gari zuri (a nice car). Do not say lizuri or jizuri for these longer adjectives (though monosyllabic ones do take ji-, like jipya). However, the Class 6 plural behaves normally and takes the ma- prefix: magari mazuri (nice cars).
• Class 9/10 (N-Class): Beginners often hear nzuri in greetings (like Habari? - Nzuri!). This is because habari is a Class 9/10 noun, which takes the n- prefix. Remember that nzuri is just one specific form, not the default word for "good"! It is used for all Class 9/10 nouns, such as nyumba nzuri (a nice house) or kazi nzuri (good work).
• Class 11/14 (U- Class): Be careful with U-class nouns! They do not take a "u-" prefix for adjectives. Instead, they share the m- prefix with Classes 1 and 3. For example, a nice wall is ukuta mzuri (not ukuta uzuri). However, Class 11 nouns usually take Class 10 for their plurals, meaning the plural reverts to the N-class rule: kuta nzuri (nice walls). Note that Class 14 nouns (which are mostly abstract concepts like uhuru) generally do not have a plural form.
• Locative Classes 16, 17, and 18: The Class 16 locative prefix is pa-. The phrase mahali pazuri (a nice place) is incredibly common and a core phrase for beginners. You can also use Class 17 ku- (kuzuri for a general nice area) and Class 18 mu- (muzuri or mzuri for a nice inside space).
• Adverbial Use: You will also frequently hear vizuri used as an adverb meaning "well" or "nicely." For example, Unaongea vizuri (You speak well).

To become confident with this word, practice matching it to the Agreement Across the Sentence for the nouns you use most often.
