Asha amesema ati atafika baadaye kidogo, kwa sababu daladala imechelewa.

Here ati introduces reported speech, similar to that in English:

• Asha amesema ati atafika... = Asha said that she will arrive...

In everyday Swahili, ati is common in speech, especially when reporting what someone said. In many contexts, it can be omitted:

• Asha amesema atafika baadaye kidogo...

That still sounds natural.
However, ati can also have other uses in Swahili depending on context, so learners often notice it and wonder why it is there.

Both relate to saying, but they differ in tense/aspect.

• amesema = has said / said with a sense of present relevance
• alisema = said in a more simple past, often more detached from the present

Breakdown of amesema:

• a- = he/she
• -me- = perfect aspect
• -sema = say

So Asha amesema... literally means something like Asha has said..., but in natural English it is often just translated as Asha said...

A learner should know that Swahili does not match English tenses one-to-one, so amesema may sound best in English as either has said or simply said, depending on context.

atafika can be broken down like this:

• a- = he/she
• -ta- = future tense marker
• -fika = arrive

So:

• atafika = he/she will arrive

Because the subject is Asha, in English we translate it as she will arrive.

This is a very useful Swahili pattern:

• atasema = she will say
• atakuja = she will come
• ataondoka = she will leave

This is a very common expression.

• baadaye = later / afterwards
• kidogo = a little / slightly

Together:

• baadaye kidogo = a little later

Even though kidogo often literally means small or a little, in time expressions it often softens the meaning:

• subiri kidogo = wait a little
• nitakuja baadaye kidogo = I’ll come a little later

So this phrase is natural and idiomatic.

Daladala is a very common East African Swahili word, especially in Tanzania. It refers to a minibus, shared public van, or local bus used for public transport.

So:

• daladala imechelewa = the minibus / local bus is delayed

A native English speaker may not recognize this word because it is cultural vocabulary rather than a basic dictionary word like gari for car/vehicle.

Because daladala is not a person, it belongs to a noun class, and the verb agreement must match that noun class.

daladala usually takes i-/zi- agreement in the singular/plural pattern commonly used for many loanwords and non-human nouns.

So:

• daladala imechelewa = the bus has been delayed / is late

Breakdown:

• i- = noun-class subject marker agreeing with daladala
• -me- = perfect aspect
• -chelewa = be late / be delayed

This is one of the big differences between Swahili and English: verbs agree not only with people like he/she, but also with noun classes.

It can mean either, depending on context.

Literally, -chelewa relates to being late or delayed, and imechelewa has a perfect sense:

• it has become late
• it is late
• it has been delayed

In this sentence, natural English is often:

• because the bus is delayed
• because the bus is late

Both are reasonable. The best choice depends on the situation.

Kwa sababu means because or for the reason that.

In this sentence:

• kwa sababu daladala imechelewa = because the bus is delayed

It is a very common and straightforward way to give a reason.

You may also see:

• kwa sababu ya... = because of...

Compare:

• Nimechelewa kwa sababu mvua ilinyesha. = I’m late because it rained.
• Nimechelewa kwa sababu ya mvua. = I’m late because of the rain.

So kwa sababu is used before a clause, while kwa sababu ya is used before a noun phrase.

Sometimes, yes, but they are not always identical in feel.

• amesema kwamba atafika...
• amesema ati atafika...

Both can mean she said that she’ll arrive...

Very roughly:

• kwamba often feels a bit more neutral or formal for that
• ati is very common in spoken reporting and can sound more conversational

However, real usage depends a lot on region and context. In everyday speech, many speakers would naturally use ati here.

Because Swahili usually puts the subject inside the verb.

For example:

• amesema = she has said
• atafika = she will arrive

The a- at the start of each verb already means he/she.

Since the name Asha is already given, Swahili does not need a separate pronoun like English does. This is very normal in Swahili.

Mostly yes, which is helpful for learners.

Swahili:

• Asha amesema ati atafika baadaye kidogo, kwa sababu daladala imechelewa.

Very literal order:

• Asha has-said that she-will-arrive later a-little, because bus is-delayed.

Natural English:

• Asha said that she’ll arrive a little later because the bus is delayed.

So the overall structure is quite similar:

1. subject
2. reporting verb
3. reported clause
4. reason clause

The biggest differences are inside the verbs, where Swahili packs subject and tense markers into one word.

A useful rule is that Swahili spelling is quite regular: words are usually pronounced much as they are written.

Approximate pronunciation:

• amesema = ah-meh-SEH-mah
• atafika = ah-tah-FEE-kah
• imechelewa = ee-meh-cheh-LEH-wah

A few helpful notes:

• a, e, i, o, u are pure vowels, not reduced like English schwa sounds
• stress is usually on the second-to-last syllable
• ch sounds like ch in church

So:

• a-me-SE-ma
• a-ta-FI-ka
• i-me-che-LE-wa

Not usually in the best translation of this exact sentence.

Because amesema is perfect aspect, it most naturally means:

• has said
• said

In context, English often prefers said:

• Asha said that she’ll arrive a little later...

If you specifically wanted Asha says, Swahili would more typically be:

• Asha anasema...

So:

• anasema = says / is saying
• amesema = has said / said

That distinction is very useful for learners.
