-m-

Class 1 Object -m-

Level 2

The infix -m- (or -mw- before vowels) is inserted into a verb to represent an animate singular object (a person or animal).

How It Works

The -m- object marker is a core part of Swahili grammar used for animate singular nouns (people and animals). Because Swahili uses Human Agreement Across Classes (the animacy hierarchy), all animate nouns (humans and animals) trigger this marker regardless of their actual noun class. It translates to 'him', 'her', or 'it' (for an animal). Note that for plural people or animals, you must use the Class 2 Object -wa- instead.

1. Placement and Form
It is placed immediately before the verb root, following the standard Verb Slot Order. For example, in ninamwona (I see him/her): ni- (Subject) + -na- (Tense) + -mw- (Object) + -on- (Root) + -a (Final Vowel). Its spelling and pronunciation change depending on the verb root:

  • Before a consonant: Use -m-. It is syllabic, meaning it is pronounced as its own distinct beat or syllable (e.g., ku-m-pi-ga / to hit him/her). If it falls on the penultimate (second-to-last) syllable, as with monosyllabic verbs, it carries the word's stress (e.g., m-pe / give him/her).
  • Before vowels: It generally changes to -mw- (e.g., ku-mw-ona / to see him/her).
  • The -mu- variant: In modern Swahili, -mu- is frequently used as an alternative before vowels, not just 'u' (e.g., ku-mu-ona / to see him/her, ku-mu-uliza / to ask him/her).

2. Obligatory Use
Unlike inanimate objects, the object marker is generally obligatory for animate nouns. You must include it whether the person or animal is specific ('the child') or non-specific ('a child').

3. Commands (Imperatives)
When you attach an object marker to a command (imperative), it forces the verb into the subjunctive mood. This means that for verbs ending in -a, the final vowel changes to -e. For example, piga (hit) becomes mpige (hit him/her). However, verbs of Arabic origin ending in -i, -e, or -u do not change their final vowel (e.g., mjibu / answer him/her). For plural commands addressed to multiple people, you must add the suffix -ni (e.g., mpigeni / hit him/her, you all).

Whom It Refers To:
-M- is third-person singular: him/her or an animate it. Compare first-person -ni- (me) and second-person -ku- (you). In mpe (give him/her), the marker supplies a syllable before the short stem -pa, and the stress-supporting ku- of kupa is absent. The final -e belongs to the object-marked command form.

Examples (4)

  1. Ninamwona mtoto.

    I see the child.

    Word by Word: I-present-him/her-see child

    Demonstrates the -mw- mutation because the verb root -ona starts with a vowel. The object marker is required here because mtoto is an animate noun.

  2. Mwalimu alimpiga mbwa.

    The teacher hit the dog.

    Word by Word: Teacher he/she-past-it-hit dog

    Demonstrates -m- before a consonant (-piga). It also shows that animals belong to Class 1 for agreement purposes.

  3. Nitamwuliza mwalimu.

    I will ask the teacher.

    Word by Word: I-future-him/her-ask teacher

    Shows the marker before the vowel 'u'. Both nitamwuliza and nitamuuliza are correct and widely used in Standard Swahili.

  4. Daktari anamsaidia mgonjwa.

    The doctor is helping the patient.

    Word by Word: Doctor he/she-present-him/her-help patient

    Shows the standard -m- marker before the consonant 's' in -saidia. Swahili does not encode gender, so this translates to helping 'him' or 'her' depending on context.

Common Mistakes

  • Leaving out the object marker when you mean a specific person or animal.

    Different MeaningNinaona mtoto.
    Ninamwona mtoto.

    Ninaona mtoto is correct when the child is not a specific one: 'I see a child'. When you mean a particular child, include -m- (or -mw-) in the verb: Ninamwona mtoto.

  • Forgetting to change -m- to -mw- before a vowel.

    Ninamona.
    Ninamwona.

    When the verb root starts with a vowel (like -ona or -ambia), the marker generally changes to -mw- to flow naturally.

  • Using -m- for inanimate objects that start with m- (Class 3).

    Ninamwona mti.
    Ninauona mti.

    The -m- object marker is only for animate nouns (Class 1). Inanimate objects like mti (tree) belong to Class 3 and use the Class 3 Object -u-.

Learn This First

To understand the Class 1 object marker '-m-', you first need to know how Swahili verbs are structured and where the object slot is located. You also need to be familiar with Noun Class 1 (people), as this marker is used specifically to represent those individuals within the verb.
