ni-

First-Person Singular Subject Ni-

Level 1

In Swahili, you don't usually use a separate word for "I". Instead, you attach the prefix ni- to the very beginning of the verb.

How It Works

The ni- prefix is an essential building block of Swahili, serving as the first-person singular subject marker meaning "I". Here is what you need to know to become confident with it:

1. Placement
It attaches to the absolute beginning of the verb. Usually, it goes directly before the tense marker (e.g., ni-li-kwenda = I went). However, in the subjunctive mood, there is no tense marker, so it attaches directly to the verb root or object marker (e.g., ni-some = let me read).

2. The Negative Shift
When making a verb negative in standard indicative tenses, ni- is highly irregular. It completely changes to si-. For example, "I do not read" is sisomi. You do not use the standard negative prefix ha- with the first person. Note that in the negative subjunctive or conditional, the ni- prefix remains intact and an internal negative infix is used (e.g., ni-si-ende = I should not go).

3. Casual Speech and Merging
In spoken Swahili, the present continuous ni-na- is frequently shortened to just na- (e.g., najua instead of ninajua "I know").

4. Common Confusions
Because the syllable ni is used for many things in Swahili, be careful not to confuse the subject prefix ni- with:

  • The standalone word ni, which means "is/am/are" (e.g., Mimi ni mwalimu = I am a teacher).
  • The object infix -ni-, which means "me" and goes in the middle of the verb (e.g., a-li-ni-ona = he saw me).
  • The locative suffix -ni, which attaches to the end of nouns to mean "in/at" (e.g., nyumbani = at home).
  • The plural imperative suffix -ni, which attaches to the end of verbs to command multiple people. Note that for verbs ending in -a, the final vowel changes to -e before adding the suffix (e.g., soma becomes someni! = read, you all!).

Habitual Hu- Is Different:
Mimi husoma kila siku means “I read every day.” Habitual hu- replaces the ordinary subject-plus-tense sequence, so do not add ni- to make nihusoma. Mimi can identify the person when context does not.

Examples (5)

  1. Ninasoma Kiswahili.

    I am studying Swahili.

    Word by Word: I-present-study Swahili.

    The prefix ni- attaches directly to the present tense marker -na-.

  2. Nilikwenda sokoni.

    I went to the market.

    Word by Word: I-past-go market-at.

    Here, ni- is used with the past tense marker -li-.

  3. Nitakuona kesho.

    I will see you tomorrow.

    Word by Word: I-future-you-see tomorrow.

    The prefix ni- is used with the future tense marker -ta-.

  4. Sisomi kitabu.

    I am not reading a book.

    Word by Word: I_not-read book.

    Notice the negative shift: ni- changes completely to si- in negative sentences.

  5. Mimi ninasoma, lakini yeye analala.

    As for me, I am reading, but he is sleeping.

    Word by Word: Me I-present-read, but him he-present-sleep.

    The independent pronoun 'mimi' is only added here to create a strong contrast between 'me' and 'him'.

Common Mistakes

  • Using 'mimi' in every sentence.

    Mimi ninasoma Kiswahili kila siku.
    Ninasoma Kiswahili kila siku.

    English speakers often unnecessarily include the independent pronoun 'mimi' (I/me). Because 'ni-' already means 'I', adding 'mimi' sounds unnatural and overly emphatic unless you are specifically contrasting yourself with someone else.

  • Applying standard negative rules to 'ni-'.

    Hanisomi kitabu.
    Sisomi kitabu.

    Learners often forget the irregular negative shift. In standard indicative tenses, the prefix 'ni-' does not take the standard negative prefix 'ha-'. Instead, it changes completely to 'si-'. (Note that 'ni-' is kept in negative subjunctive and conditional forms, such as 'nisiende').

  • Writing the prefix as a separate word.

    Ni nasoma.
    Ninasoma.

    Swahili is an agglutinative language, meaning word parts stick together. The subject marker 'ni-' must be attached directly to the rest of the verb, not written with a space.
