Baada ya kutembea kwa muda mrefu, kisigino cha Rahma kiliuma kuliko kiuno chake.

Baada ya means after.

In Swahili, baada ya + infinitive is a very common way to say after doing something. So:

• baada ya kutembea = after walking
• literally: after to-walk / after walking

You can also use baada ya before a noun:

• baada ya chakula = after the meal
• baada ya kazi = after work

So in this sentence, Baada ya kutembea kwa muda mrefu means After walking for a long time.

The ku- form is the infinitive, like to walk in English.

In many Swahili structures, the infinitive acts like an English -ing form or verbal noun. After baada ya, Swahili normally uses this infinitive form:

• kutembea = to walk / walking
• kusoma = to read / reading
• kulala = to sleep / sleeping

So although English says after walking, Swahili uses the infinitive: baada ya kutembea.

Kwa muda mrefu means for a long time.

Breakdown:

• kwa = a very common preposition with meanings like by, with, for, in a manner of, depending on context
• muda = time / period
• mrefu = long

Together, kwa muda mrefu is an idiomatic expression meaning for a long time.

So:

• kutembea kwa muda mrefu = to walk for a long time

Here kwa helps form a time-expression. It is not translated word-for-word very neatly into English, but the whole phrase is natural Swahili.

Swahili usually shows possession with a connector that agrees with the possessed noun.

Here:

• kisigino = heel
• cha = possessive connector meaning of, agreeing with kisigino
• Rahma = the possessor

So:

• kisigino cha Rahma = Rahma's heel
• literally: heel of Rahma

The important point is that cha is chosen because kisigino belongs to noun class 7, which uses cha in this kind of possessive structure.

This pattern is very common:

• kitabu cha Juma = Juma's book
• kisu cha mama = mother's knife

Kiliuma agrees with kisigino, which is the subject of the verb.

Breakdown:

• ki- = subject prefix for noun class 7
• -li- = past tense
• -uma = verb root

So:

• ki-li-uma = it hurt / it ached

Because kisigino is a class 7 noun, the verb takes ki-.

This is a key feature of Swahili: verbs agree with the noun class of the subject.

Compare:

• mguu uliuma = the leg hurt
• jicho liliuma = the eye hurt
• kisigino kiliuma = the heel hurt

Yes, -uma can mean different but related things depending on context.

Common meanings include:

• to bite / sting
• to hurt / ache / be painful

In this sentence, the subject is a body part:

• kisigino kiliuma = the heel hurt / the heel ached

So this is clearly the hurt/ache meaning, not bite.

This kind of usage is very natural in Swahili. A body part can be the grammatical subject:

• kichwa kinauma = my/the head hurts
• jino linauma = my/the tooth hurts

Literally these often look like the head is hurting, the tooth hurts, and so on.

Kuliko means than in comparisons.

So:

• kiliuma kuliko kiuno chake = hurt more than her waist

It introduces the second item in the comparison.

Structure:

• X ... kuliko Y = X ... than Y

In this sentence:

• kisigino cha Rahma kiliuma kuliko kiuno chake
• Rahma's heel hurt more than her waist

You can use kuliko with verbs, adjectives, and other comparisons:

• ni mkubwa kuliko mimi = he/she is bigger than me
• anafanya kazi kuliko wewe = he/she works more than you

Both are possible, but kiuno chake is more natural because once Rahma has already been mentioned, Swahili often switches to a possessive pronoun.

Here:

• kiuno = waist/hip
• cha- + -ke = chake = his/her, agreeing with kiuno

So:

• kiuno chake = his/her waist
• literally: waist his/her

Swahili possessive forms must agree with the noun being possessed, not with the person who owns it. Since kiuno is class 7, the possessive form is chake, not just a single fixed word for her.

So:

• kisigino cha Rahma = Rahma's heel
• kiuno chake = her waist

Using kiuno cha Rahma would also be grammatical, but kiuno chake is smoother and less repetitive.

Chake can mean his or her.

Swahili does not usually distinguish gender in third-person singular possessives:

• wake
• lake
• chake
• etc.

The exact form depends on noun class, but not on whether the person is male or female.

So kiuno chake could mean:

• his waist
• her waist

In this sentence, because the person already mentioned is Rahma, the natural interpretation is Rahma's waist, and since Rahma is usually a woman's name, English would normally translate it as her waist.

Because both nouns belong to the same noun class: class 7 in the singular.

• kisigino = class 7
• kiuno = class 7

That is why you see the same kind of agreement:

• ki- in the verb: kiliuma
• cha in cha Rahma
• ch- in chake

This is one of the most important things to notice in Swahili: words around the noun often change form to match the noun class.

So the sentence is a good example of class agreement:

• kisigino cha Rahma ki-li-uma
• kiuno chake

Once you learn to spot noun classes, sentences like this become much easier to understand.
