Grammar Rule in 30 Seconds

When using monosyllabic verbs in the present tense, you must keep the 'ku-' prefix to maintain the verb's structure.

  • Monosyllabic verbs (e.g., -la, -nywa) keep 'ku' in the present tense: 'Ninakula' (I am eating).
  • In the negative, the 'ku' is dropped: 'Sili' (I am not eating).
  • In other tenses like the past (-li-) or future (-ta-), the 'ku' is dropped: 'Nilikula' (I ate).

Little Verb 'La' was very short. He went to the Present Tense party and wore a 'ku-' hat to look taller. But when he went to the Negative party, he took his hat off because he wanted to look tough. When he went to the Past party, he didn't need the hat at all.

Eating is a communal activity. Using 'ninakula' is a common way to invite others to join.

In Nairobi slang, 'nakula' can sometimes be used to mean 'I am making money'.

The usage of these verbs is very standard, but pronunciation might be slightly more elongated.

The 'ku-' prefix is a remnant of the Bantu class 15 noun marker, which functions as an infinitive.
