Kesho, dada yangu ataenda saluni kutengeneza nywele kabla ya sherehe.

Yes. Kesho means tomorrow, and time expressions are quite flexible in Swahili. Putting it first sets the time frame right away, like Tomorrow, ... in English.

You could also say something like Dada yangu ataenda saluni kesho.... Starting with kesho is just a very natural choice.

Dada means sister, and yangu means my here.

A useful thing to memorize is that many common kinship words use forms like yangu, yako, yake in the singular:

• mama yangu = my mother
• baba yangu = my father
• kaka yangu = my brother
• dada yangu = my sister

So dada yangu is simply the normal way to say my sister.

Because in Swahili, the verb normally includes a subject marker even when the full subject noun is also stated.

So in ataenda:

• a- = he/she
• -ta- = future
• -enda = go

That means the sentence is structurally a bit like My sister, she will go.... This is normal Swahili grammar, not awkward repetition.

It breaks down as:

• a- = subject marker for he/she
• -ta- = future tense marker
• -enda = verb root go

So ataenda means he/she will go.

Swahili does not match English prepositions word-for-word. With a verb like kuenda (to go), the destination often comes directly after the verb.

So:

• kuenda saluni = to go to the salon

You may also hear longer location expressions in other contexts, but here saluni by itself is perfectly natural.

Here kutengeneza is an infinitive used to show purpose.

After a verb of movement like go, Swahili often uses ku- + verb to mean in order to ...

So:

• ataenda saluni kutengeneza nywele
• she will go to the salon to do/fix her hair

This pattern is very common.

Literally, kutengeneza can mean make, fix, arrange, or prepare.

With nywele (hair), it usually means something like:

• do one's hair
• arrange one's hair
• fix one's hair

So it is an everyday, natural expression. If you wanted to be more specific, Swahili can also use verbs for particular hair actions, but kutengeneza nywele is a broad and useful phrase.

Because the owner is already clear from context.

Once the sentence has dada yangu as the subject, nywele will naturally be understood as her hair. Swahili often leaves out possessives when they are obvious, especially with body parts or things closely associated with the person.

If you wanted extra emphasis or clarity, you could say nywele zake, but it is not necessary here.

In everyday Swahili, nywele is the normal word for hair as a collective idea. Grammatically, it behaves like a plural-type noun.

So:

• nywele = hair
• unywele mmoja = one hair, one strand of hair

A learner should mainly remember that nywele is the usual word for hair in general.

Kabla ya means before.

It can be understood as:

• kabla = before
• ya = linking word
• sherehe = party, celebration

So kabla ya sherehe means before the party.

The ya is important here. You would not normally leave it out.

Swahili does not have articles that work like English the and a/an.

So words like saluni and sherehe appear without separate article words. Whether the meaning is a salon, the salon, a party, or the party is understood from context.

Often, yes. Swahili word order is fairly flexible, especially with time expressions like kesho.

This sentence is very natural as written:

• Kesho = time
• dada yangu = subject
• ataenda saluni = main action
• kutengeneza nywele = purpose
• kabla ya sherehe = before the party

You could move some parts around, especially kesho, but the given order sounds smooth and idiomatic.
