Baba atasoma ilani ya chama atakachokiunga mkono.

Atasoma breaks down as:

• a- = he/she
• -ta- = future tense
• -soma = read / study

So atasoma means he will read. In this sentence, the he refers to Baba.

Ya is the associative marker, often translated as of. So ilani ya chama means the manifesto of the party.

A useful detail: this connector agrees with ilani, not with chama. Since ilani is a class 9 noun, the associative form is ya.

It describes chama. So the structure is:

• ilani ya chama = the manifesto of the party
• atakachokiunga mkono = that he will support

Together: the manifesto of the party that he will support.

It does not describe ilani.

A helpful breakdown is:

• a- = he
• -ta- = future
• -ka- = part of the future relative construction
• -cho- = relative marker agreeing with chama
• -ki- = object marker referring to chama
• -unga mkono = support

So the whole form means something like that he will support it, where it refers to the party.

They do two different jobs:

• -cho- means which/that, and it links the clause to chama
• -ki- shows that chama is the object of support

So Swahili packs a lot of information into one verb form. English uses separate words, but Swahili often builds those meanings into the verb itself.

Because agreement is based on noun class, not just on the first letters of the word. Chama is a class 7 singular noun, and the class 7 relative marker is -cho-.

You can see its class more clearly in the plural:

• chama = singular
• vyama = plural

That ki/vi pattern is class 7/8, even though the singular form chama is irregular in shape.

Yes, it is written as two words: kuunga mkono. As a whole, it means to support or to back.

Literally, it comes from ideas like join + hand, so the imagery is close to lend a hand or back someone/something. In normal use, though, learners should treat kuunga mkono as a single idiomatic expression meaning support.

Not here. Instead of using a separate word like English that or which, Swahili often uses a relative marker inside the verb. In this sentence, that marker is -cho-.

So atakachokiunga mkono already contains the idea of that he will support.

Yes. A more analytic version would be:

Baba atasoma ilani ya chama ambacho atakiunga mkono.

That also means the same thing. The original sentence uses the shorter built-in relative form, while the amba- version may feel easier for learners to spot and understand.
