Swahili Grammar Guide

“I was, it is, she’ll be” using “to be” in Swahili: ni/si and kuwa

In the present tense, ni is used with every pronoun to say “to be”.

In past and future tenses, we use kuwa.

Pronoun Past Present Future
mimi nilikuwa ni nitakuwa
wewe ulikuwa ni utakuwa
yeye alikuwa ni atakuwa
sisi tulikuwa ni tutakuwa
ninyi mlikuwa ni mtakuwa
wao walikuwa ni watakuwa
“It” e.g. i haikuwa ni itakuwa

Negative form of “to be”: Kuwa also behaves strangely in the present tense for negations:

  • In the present tense, si is used with every pronoun.
  • In the past tense, the negation prefix ku is optional as it's redundant (and most people leave it out, so I will leave it out here).
Pronoun Past Present Future
mimi sikuwa si sitakuwa
wewe hukuwa si hutakuwa
yeye hakuwa si hatakuwa
sisi hatukuwa si hatutakuwa
ninyi hamkuwa si hamtakuwa
wao hawakuwa si hawatakuwa

A few examples of conjugating kuwa:

English Swahili
I’ll be at school Nitakuwa shuleni.
Where were you yesterday? Ulikuwa wapi jana?
They weren’t home yesterday. Hawakuwa nyumbani jana.
You won’t be at the office. Hutakuwa ofisini.
