"I don't know" in Swahili 路 say it like see-joo-ee

The most natural way to say "I don't know" in Swahili is sijui. Tap the speaker above to hear it, then say it back out loud. That is the fastest way to make it stick.

Other ways to say it

sijui kabisa
used for emphasis, meaning 'I really don't know'
sijui sana
used to express a stronger sense of uncertainty

When to use it

You can use 'sijui' in casual conversations when you are unsure about something. It is appropriate in both formal and informal settings. Use it when someone asks you a question and you genuinely do not have the answer.

Say it out loud, get corrected

Reading it is not the same as saying it. Practice "I don't know" and thousands more with an AI coach that listens.

Examples in Swahili

SwahiliEnglish
Nina swali, lakini sijui.I have a question, but I don't know.
Je, unajua wapi alipo? Sijui.Do you know where he is? I don't know.
Common mistake
Learners often confuse 'sijui' with 'sijui nini', which is more specific and means 'I don't know what'.
