kwa sababu

Reason with Kwa Sababu

Level 1

Kwa sababu means "because" and is the most common way to explain why something happens in Swahili.

How It Works

The phrase kwa sababu literally translates to "for the reason" and is used exactly like "because" in English. It is a neutral, everyday expression appropriate for both casual conversations and formal writing.

There are two main ways to use it depending on what follows:

  • Kwa sababu + Full Sentence: When followed by a subject and a verb, use it just as it is. For example: Nimechoka kwa sababu nilifanya kazi sana (I am tired because I worked a lot).
  • Kwa sababu ya + Noun: When followed directly by a noun to mean "because of," you must add the word ya. For example: kwa sababu ya mvua (because of the rain).

Important Notes:

  • Spelling: Always write it as two separate words. You might see people write kwasababu in informal text messages, but standard Swahili requires a space.
  • Answering Questions: It is the standard way to answer a question that begins with Why with kwa nini.
  • Cause vs. Effect: Be careful not to confuse it with Therefore with kwa hiyo. Kwa sababu introduces the cause, while kwa hiyo introduces the result.

Examples (4)

  1. Ninasoma Kiswahili kwa sababu ninapenda lugha.

    I am studying Swahili because I like languages.

    Word by Word: I am studying Swahili for reason I like languages.

    Here, kwa sababu is followed by a full clause (ninapenda lugha).

  2. Sikuenda kazini kwa sababu nilikuwa mgonjwa.

    I didn't go to work because I was sick.

    Word by Word: I did not go to work for reason I was sick.

    Another example of kwa sababu connecting an action to its reason using a full sentence.

  3. Tulichelewa kwa sababu ya mvua kubwa.

    We were late because of the heavy rain.

    Word by Word: We were late for reason of rain big.

    Because "mvua kubwa" (heavy rain) is a noun phrase, we must use "kwa sababu ya" (because of).

  4. Sipendi mji huu kwa sababu ya msongamano.

    I don't like this city because of the traffic.

    Word by Word: I do not like city this for reason of traffic.

    Again, "msongamano" (traffic) is a noun, requiring the addition of "ya".

Common Mistakes

  • Forgetting to use 'ya' when saying 'because of' a noun.

    Tulichelewa kwa sababu mvua.
    Tulichelewa kwa sababu ya mvua.

    When followed directly by a noun (like rain, traffic, or a person), you must use the associative particle 'ya' to mean 'because of'.

  • Writing the phrase as a single word.

    Nimechoka kwasababu nilikimbia.
    Nimechoka kwa sababu nilikimbia.

    Although often pronounced quickly or written as one word in informal texting, standard Swahili strictly requires it to be written as two separate words.
