Number Agreement with Nouns
Grammar Rule in 30 Seconds
In Swahili, numbers must 'agree' with the noun they describe by using a specific prefix based on the noun's class.
- Numbers 1-5 change their prefix to match the noun class: 'mtu mmoja' (one person).
- Numbers 6-10 are generally invariant and do not change their prefix.
- The prefix used for the number is usually the same as the noun's class prefix.
