Samahani kwa kuchelewa, rafiki.

In this sentence, samahani means sorry or forgive me.

It is a very common Swahili word used for:

• apologizing: Sorry
• getting attention politely: Excuse me
• asking someone to repeat something politely

So in Samahani kwa kuchelewa, rafiki, it introduces the apology.

Kwa here means something like for.

So:

• samahani = sorry
• kwa kuchelewa = for being late

This is a common pattern in Swahili:

• Samahani kwa usumbufu = Sorry for the inconvenience
• Asante kwa kusaidia = Thank you for helping

So kwa often links an emotion or reaction to its reason.

Kuchelewa comes from the verb -chelewa, which means to be late or to delay.

The ku- at the beginning is the infinitive marker, like to in English:

• chelewa = be late
• kuchelewa = to be late / being late

After kwa, this infinitive often works like an English -ing form:

• kwa kuchelewa = for being late

Because kuchelewa is not a full conjugated verb here. It is an infinitive/verbal noun.

In English, we say:

• Sorry for being late

Not:

• Sorry for I am late

Swahili is doing something similar:

• kwa kuchelewa = for being late

If you wanted a full sentence with a subject, you could say something like:

• Nimechelewa = I am late / I have been late

But in this apology, the infinitive structure is the natural choice.

Rafiki means friend, and here it is being used as a form of address, like calling someone friend directly.

So:

• Samahani kwa kuchelewa, rafiki. means
• Sorry for being late, friend.

It is optional. If you remove it, the sentence still works:

• Samahani kwa kuchelewa. = Sorry for being late.

Here it is singular: friend.

The usual plural is marafiki:

• rafiki = friend
• marafiki = friends

So if speaking to more than one friend, you might say:

• Samahani kwa kuchelewa, marafiki.

Yes, it is natural and polite.

Samahani kwa kuchelewa is a normal way to apologize for lateness. It is polite without being overly formal.

Depending on context, you might also hear:

• Samahani nimechelewa = Sorry, I’m late
• Pole kwa kuchelewa is less standard for apologizing about your own lateness; samahani is the safer choice here.

So for a learner, Samahani kwa kuchelewa is a very good phrase to remember.

A simple pronunciation guide is:

sa-ma-HA-ni kwa ku-che-LE-wa ra-FI-ki

A few helpful points:

• Swahili vowels are usually pure and consistent:
  • a as in father
  • e as in bet but often clearer
  • i as in machine
  • o as in go but without a strong glide
  • u as in rule
• ch sounds like ch in church
• Stress in Swahili often falls on the second-to-last syllable:
  • sa-ma-HA-ni
  • ku-che-LE-wa
  • ra-FI-ki

Only roughly.

A close word-for-word breakdown is:

• Samahani = sorry / forgive me
• kwa = for
• kuchelewa = to be late / being late
• rafiki = friend

So the natural English translation is:

• Sorry for being late, friend.

A very literal version like Forgiveness for being late, friend would not sound natural in English, even though it helps show the structure.

Yes. That is one reason learners hear it so often.

Samahani can be used for:

• Sorry
• Excuse me
• Pardon me

For example:

• Samahani, unaweza kusaidia? = Excuse me, can you help?
• Samahani kwa kuchelewa. = Sorry for being late.

The exact meaning depends on context. In your sentence, it clearly means an apology.
