Class 3 Object -u-

Level 3

The infix -u- is the object marker for singular Class 3 nouns (like mti or mkate). It translates to 'it' and is placed directly before the verb root.

How It Works

Understanding how to use the Class 3 object marker involves a few key rules:

  • Placement: It follows the standard Verb Slot Order. The structure is: Subject + Tense + Object (-u-) + Stem (Root + Final Vowel). The object marker always hugs the verb stem, even in negative constructions. For example: ni-li-u-kata (I cut it) and si-ku-u-kata (I did not cut it).
  • The Golden Rule: For inanimate noun classes like Class 3, the object marker is exactly the same as its subject prefix. For Class 3, both are -u-. This makes it easy to remember! For example: Mti ulianguka (The tree fell) -> Niliukata (I cut it).
  • Optional vs. Mandatory: Unlike animate nouns, inanimate object markers are optional when the noun is present. Nilikata mti (I cut a tree) is perfectly grammatical. Adding -u- (Niliukata mti) emphasizes 'the tree' or focuses on it. If the noun is omitted, -u- is mandatory: Niliukata (I cut it).
  • Monosyllabic Verbs: Verbs like kula (to eat) usually keep their infinitive ku- prefix to carry stress (e.g., nilikula). However, when you add the -u- object marker, it acts as a syllable that can carry stress, so the ku- is dropped! So, 'I ate it' (referring to mkate) is niliula in standard grammar. (Note: While niliula is the standard rule, you may still hear niliukula in colloquial speech). This is a classic example of Short Verbs with an Object Marker.
  • Vowel-Commencing Verbs: The Class 3 object marker -u- does not change to w- before verbs that start with a vowel. It remains -u-. For example, 'I saw it' (referring to mti) is niliuona, not niliwona.
  • Don't confuse with Class 1: Both Class 1 (people) and Class 3 (things) nouns start with the prefix m-. Because of this, learners often accidentally use the Class 1 object marker -m- for trees and objects. Remember: Class 1 takes -m-, while Class 3 takes -u-.
  • Don't confuse with "you": Because the second-person singular subject prefix is u- (you), English speakers frequently assume the object marker for "you" is also -u-. However, the object marker for "you" is actually Second-Person Object -ku-. The -u- object marker is strictly for Class 3 (and Class 11/14) nouns!
  • Singular Only: Remember that Class 3 is strictly singular. For plural Class 4 nouns (like miti), you must use the Class 4 Object -i- instead.

  1. Mwalimu alitoa mfano mzuri; tusije tukaupuuza.

    The teacher gave a good example; lest we ignore it.

    Word by Word: Teacher gave example good; lest we-ignore-it.

    Here, -u- acts as a mandatory pronoun for the omitted Class 3 noun 'mfano' (example).

  2. Umeuona mkoba wangu? Ndiyo, ninauona.

    Have you seen my bag? Yes, I see it.

    Word by Word: You-have-it-seen bag my? Yes, I-present-it-see.

    Shows -u- attaching to a vowel-initial root '-ona'. In the question, it marks the specific bag. In the answer, it acts as 'it'.

  3. Niliukata mti.

    I cut the tree.

    Word by Word: I-past-it-cut tree.

    Including the object marker when the noun is present makes the object definite ('the tree' rather than 'a tree').

  4. Mkate huu ni mtamu, niliula asubuhi.

    This bread is delicious, I ate it in the morning.

    Word by Word: Bread this is delicious, I-past-it-eat morning.

    Demonstrates the dropping of 'ku-' on the monosyllabic verb 'kula' (to eat). It becomes 'niliula', not 'niliukula'.

Common Mistakes

  • Overgeneralizing the -m- object marker for all nouns starting with m-.

    Nilimkata mti.
    Niliukata mti.

    Because both Class 1 (people, like 'mtu') and Class 3 (things, like 'mti') start with 'm-', learners often use the animate object marker '-m-' for everything. You must use '-u-' for inanimate Class 3 nouns.

  • Keeping the 'ku-' prefix on monosyllabic verbs when using an object marker.

    Niliukula mkate.
    Niliula mkate.

    When you add an object marker to a short verb like 'kula' (to eat) or 'kunywa' (to drink), the 'ku-' prefix must be dropped because the object marker provides the necessary syllable for stress.
