how to identify and use U-I noun class (Nomino za ngeli ya U-I) in Kiswahili. This beginner-friendly guide for Senior One also explains punctuation marks (Alama za uakifishaji) with examples and translations.
Introduction: Why Grammar and Punctuation Matter in Kiswahili
When learning any new language, it’s important to understand how words are grouped and how sentences are structured. In Kiswahili, nouns are organized into noun classes, and each class has its own rules for singular and plural forms. Today, we will learn about one of these classes—Ngeli ya U-I (U-I noun class).
We’ll also learn about punctuation marks, which are important for writing clear and correct Kiswahili sentences.
1. Nomino za Ngeli ya U-I (U-I Class Nouns in Kiswahili)
What is a Noun Class?
A noun class in Kiswahili is a group of nouns that behave the same way in sentence construction. They have similar prefixes for singular and plural, and they affect the form of verbs, adjectives, and pronouns in a sentence.
U-I Noun Class Overview
This noun class includes nouns that begin with “u-“ in singular and change to “i-“ or “zi-“ in plural. Most of these nouns represent non-human things like natural features, abstract ideas, or materials.
Examples of U-I Noun Class (With Translations)
| Singular (U-) | Plural (I-/Zi-) | Meaning (English) |
| Uzi | Nyuzi | Thread |
| Ubao | Mbao | Wooden plank |
| Ufunguo | Funguo | Key |
| Uzi | Nyuzi | Thread |
| Ua | Maua | Flower |
| Ulimi | Ndimi | Tongue |
🔎 Note: Not all nouns follow a strict “U-I” pattern. Some irregular forms exist, and it’s important to learn them through practice.
How U-I Nouns Work in Sentences
Example 1:
- Ufunguo umeanguka.
(The key has fallen.) - Funguo zimeanguka.
(The keys have fallen.)
Example 2:
- Ubao uko jikoni.
(The plank is in the kitchen.) - Mbao ziko jikoni.
(The planks are in the kitchen.)
2. Subject and Object Agreement in U-I Noun Class
In Kiswahili, verbs change based on the noun class. For the U-I noun class:
Subject Prefixes
| Number | Prefix | Example Sentence |
| Singular | u- | Ufunguo umevunjika. (The key is broken.) |
| Plural | zi- | Funguo zimevunjika. (The keys are broken.) |
Object Prefixes
| Number | Prefix | Example Sentence |
| Singular | u- | Nimeuona ufunguo. (I have seen the key.) |
| Plural | zi- | Nimeziona funguo. (I have seen the keys.) |

3. Alama za Uakifishaji (Punctuation Marks in Kiswahili)
Why is Punctuation Important?
Punctuation (alama za uakifishaji) helps in organizing sentences and showing pauses, questions, or strong emotions in writing. Without punctuation, it becomes difficult to understand the meaning of a sentence.
Common Punctuation Marks and Their Kiswahili Terms
| Punctuation Mark | Kiswahili Name | Function | Example |
| . | Nukta | Shows the end of a sentence | Ninaenda shuleni. (I am going to school.) |
| , | Koma | Indicates a pause | Tafadhali, njoo hapa. (Please, come here.) |
| ? | Alama ya kuuliza | Used in questions | Unafanya nini? (What are you doing?) |
| ! | Alama ya mshangao | Shows strong emotion or command | Kimbia haraka! (Run quickly!) |
| : | Nukta mbili | Introduces a list | Leta vitu hivi: kalamu, daftari, na kitabu. |
| ” “ | Alama za kunukuu | Shows direct speech or quotations | Alisema, “Ninajifunza Kiswahili.” |
