na

The word na serves several key functions in Swahili:

1. As "And" (Conjunction)
You can use na to join nouns, names, or phrases.
Example: Juma na Maria (Juma and Maria).
⚠️ Crucial Rule: When na joins two subjects, they become plural. The verb that follows MUST take a plural subject prefix matching the persons involved. For example, Juma na Maria becomes "they" (wanakula), but mimi na Juma becomes "we" (tunakula). When joining two inanimate nouns of different classes, the verb typically defaults to the Class 8 vi- prefix (e.g., Kiti na meza vimevunjika - The chair and table are broken). However, in modern spoken Swahili, it is also very common to use last-conjunct agreement, where the verb takes the prefix of the noun closest to it (e.g., Kiti na meza imevunjika, taking the Class 9 i- prefix to agree with meza).

2. Joining Two Actions
When a person does two closely linked actions in a single incident, you can use na followed by the infinitive form (e.g., Alianguka na kuumia - He fell and got hurt). While the narrative -ka- tense is used for a sequence of separate events, na + infinitive is perfectly natural and common for closely connected actions.

3. As "With" (Accompaniment)
na means "together with a person or thing."
Example: Ninaenda na rafiki (I am going with a friend).
⚠️ Note on Instruments: In Standard Swahili, you should use kwa for tools or instruments (e.g., kwa kalamu - with a pen). However, in casual street speech, you will frequently hear native speakers use na for instruments as well.

4. Pronoun Contractions
na can contract when followed by a personal pronoun. The complete set for human pronouns is: nami (with me), nawe (with you), naye (with him/her), nasi (with us), nanyi (with you all), and nao (with them). It also merges with the o-reference pronoun (also known as the relative concord) for different noun classes (e.g., nacho, nalo, nazo). These contractions are vital for expressing "to have it" or "to have them" (e.g., ninacho - I have it [class 7]).

5. "To Have" and Expressing States
Swahili does not have a standalone verb for "to have." Instead, it uses kuwa na (literally "to be with"). For example, nina kitabu means "I have a book." Additionally, Swahili uses kuwa na + [noun] to express physical states or feelings that are expressed as adjectives in English. For example, nina njaa (I am hungry, literally "I have hunger") or tuna bahati (we are lucky, literally "we have luck").

6. Passive Agent ("By")
In passive sentences, na is used to indicate who performed the action, acting like "by" in English. For example, using the na passive agent: Chakula kilipikwa na mama (The food was cooked by mother).

7. With Reciprocal Verbs
Verbs ending in the reciprocal -ana suffix (meaning "each other") require na to introduce the second party. For example, Ninaonana na Juma (I am meeting with Juma).

8. Disambiguation: The -na- Tense
Do not confuse the standalone word na with the present tense -na- marker. The tense marker is attached inside the verb (e.g., ninasoma - I am reading), while the conjunction na is a separate word.

9. Expressing Existence ("There is / There are")
When na is attached to locative prefixes (ku-, pa-, mu-), it expresses existence. For example, kuna means "there is" or "there are" (e.g., kuna watu - there are people), and hakuna means "there is no" or "there are no" (e.g., hakuna matata - there are no problems).
