The Simple Past in Swahili: Constructing the Tense with Verbs

As with other languages, Swahili’s Simple Past tense is employed to describe actions that took place and were completed in the past. The main aspect to consider when forming this tense is the appropriate conjugation of the verb.

In Swahili, the Simple Past tense is predominantly formed by adding the infix -li- to the verb stem, directly after the subject prefix. This structure is utilized for all persons and numbers, simplifying conjugation significantly.

Let’s take a closer look at the verb kula (‘to eat’) as an example:

• Mimi (I) → Nilikula (I ate)
• Wewe (You) → Ulikula (You ate)
• Yeye (He/She) → Alikula (He/She ate)
• Sisi (We) → Tulikula (We ate)
• Ninyi (You, pl.) → Mlikula (You, pl., ate)
• Wao (They) → Walikula (They ate)

Bear in mind that we maintain the general structure of subject prefix + -li- + verb stem for virtually all verbs when conjugating in the Simple Past.

Exceptions and Irregularities in the Swahili Simple Past

Despite the supposed simplicity of Swahili’s Simple Past tense, certain verbs demand attention due to their irregular conjugation patterns.

The verb kuwa (to be) is particularly noteworthy in this respect. It takes the following unique form in the Simple Past:

• Mimi (I) → Niliwahi (I was)
• Wewe (You) → Uliwahi (You were)
• Yeye (He/She) → Aliwahi (He/She was)
• Sisi (We) → Tuliwahi (We were)
• Ninyi (You, pl.) → Mliwahi (You, pl., were)
• Wao (They) → Waliwahi (They were)

In the case of monosyllabic verb roots (verbs with just one syllable), the infix -li- is replaced with -li and is added after the verb stem. Take, for instance, the monosyllabic verb toa (‘to give’):

• Mimi (I) → Nilitoa (I gave)

Using the Simple Past in Negative Forms and Questions

To negate a verb in Swahili’s Simple Past, simply replace the infix -li- with -ku-, followed by the infix -ja-:

• Mimi (I) → Nisitoa (I did not give)

In order to pose questions in the Simple Past tense, place the question word at the beginning of the sentence and swap the subject prefix and tense infix:

• Je, ulikula? (Did you eat?)
