N-Class Adjective Agreement

Level 2

Class 9/10 nouns use the N- prefix for adjectives, but this prefix changes shape (or disappears entirely) depending on the first letter of the adjective.

How It Works

The Class 9/10 adjective agreement is one of the most dynamic patterns in Swahili. Because the 'N' sound interacts differently with various consonants, the prefix changes to make pronunciation easier.

Here are the essential rules for Bantu-origin adjectives:

  • Before d, g, z, j: The prefix is n- (e.g., -dogo (small) → ndogo, -zuri (good) → nzuri, -jinga (foolish) → njinga).
  • Before b, v: The prefix becomes m- (e.g., -baya (bad) → mbaya).
  • Before w: The 'w' changes to 'b' and takes 'm-', becoming mb- (e.g., -wili (two) → mbili).
  • Before vowels: It becomes ny- (e.g., -eupe (white) → nyeupe, -ingi (many) → nyingi, -ingine (other) → nyingine), except for -ema (good) which becomes njema, -ovu (evil/wicked) which becomes mbovu, and -ume (male) which becomes dume or ndume.
  • Before r, l: The r/l changes to d, making nd- (e.g., -refu (long/tall) → ndefu).
  • Before voiceless consonants (k, p, t, s, sh, f, ch) and nasals (m, n): The prefix drops entirely (e.g., -kubwa (big) → kubwa, -fupi (short) → fupi, -shupavu (brave) → shupavu, -nene (thick/fat) → nene). Note that when dropping before voiceless consonants like k, p, t, and ch, the consonant is often pronounced with a slight puff of air (aspiration).

Important Exceptions & Notes:

  • Numbers: Swahili numbers 1-5 and 8 take adjective concords and follow these exact Class 9/10 rules (e.g., -moja (one) → moja, -wili (two) → mbili, -tatu (three) → tatu, -nne (four) → nne, -tano (five) → tano, -nane (eight) → nane).
  • Monosyllabic adjectives: These retain a prefix to carry stress. For example, -pya (new) becomes mpya (the prefix assimilates to 'm-' because 'p' is a bilabial consonant).
  • Loanwords: Arabic adjectives like safi (clean) or ghali (expensive) take no prefix at all.
  • Animate nouns: Animals and people in Class 9/10 (like mbwa (dog) or rafiki (friend)) must use M-WA adjective agreement instead. For possessives, human Class 9/10 nouns (e.g., rafiki) take N-class possessives (yangu/zangu), whereas animal Class 9/10 nouns (e.g., mbwa) often take Class 1 possessives in the singular and Class 10 possessives in the plural (wangu/zangu), but animate plural possessives such as wangu are also used, with context or numerals identifying plurality.
  • Possessives and Special Roots: Possessives (like -angu or -ako) and special roots (like -ote or -enye) do not take the N- prefix. Instead, they use the pronominal prefixes y- for Class 9 (singular) and z- for Class 10 (plural) (e.g., yangu / zangu, yote / zote).

Examples (5)

  1. Nyumba nzuri inatosha.

    A beautiful house is enough.

    Word by Word: House good it-suffices.

    Before 'z', the prefix remains 'n-' (-zuri → nzuri).

  2. Nguo mpya ni ghali.

    New clothes are expensive.

    Word by Word: Clothes new are expensive.

    The monosyllabic adjective '-pya' retains a prefix to carry stress, which assimilates to 'm-' because 'p' is a bilabial consonant (mpya). The Arabic loanword 'ghali' takes no prefix.

  3. Kalamu yako ni fupi.

    Your pen is short.

    Word by Word: Pen your is short.

    Before the voiceless consonant 'f', the N- prefix drops entirely (-fupi → fupi).

  4. Njia ndefu inachosha.

    A long road is tiring.

    Word by Word: Road long it-tires.

    Before 'r', the consonant mutates to 'd', creating the 'nd-' prefix (-refu → ndefu).

  5. Tuna kazi nyingi leo.

    We have a lot of work today.

    Word by Word: We-have work much today.

    Before a vowel, the prefix becomes 'ny-' (-ingi → nyingi).

Common Mistakes

  • Failing to drop the prefix before voiceless consonants (k, p, t, s, f, ch) or nasals (m, n).

    Kazi nkali.
    Kazi kali.

    Before voiceless consonants like 'k' or nasals like 'n', the N- prefix drops entirely. You do not say 'nkali', 'ntamu', or 'nnene'.

  • Missing the r → d mutation for adjectives starting with 'r' or 'l'.

    Safari nrefu.
    Safari ndefu.

    When the N- prefix attaches to an adjective starting with 'r' or 'l' (like -refu), the consonant mutates to 'd', creating 'nd-'.

  • Applying N-class rules to animate nouns (animals/people) in Class 9/10.

    Mbwa ndogo.
    Mbwa mdogo.

    Animate nouns always take Class 1/2 (M-/Wa-) agreement, regardless of their noun class. Therefore, 'mbwa' takes 'mdogo', not 'ndogo'.
