Jumla ya mbaazi tulizonunua leo inatosha kwa chakula cha siku mbili.

Jumla means total, sum, or overall amount.
The linker ya means of here, so jumla ya mbaazi means the total amount of peas or the total of the peas.

This is a very common pattern in Swahili:

• jumla ya pesa = the total amount of money
• idadi ya watu = the number of people
• kikombe cha chai = a cup of tea

So jumla ya mbaazi is a noun phrase meaning the total quantity of peas.

Ya is a genitive/associative connector, often translated as of.

In Swahili, this connector changes to match the noun that comes before it. Since jumla belongs to a noun class that takes ya, we say:

• jumla ya mbaazi

not some other connector like wa, cha, or za.

So the pattern is:

• jumla
  • ya
    • thing being totaled

This is one of the most common structures in Swahili.

Mbaazi usually refers to peas or pigeon peas, depending on context. In everyday learning, you can think of it as a noun meaning peas.

Grammatically, it behaves like a noun in the N/N class (often called class 9/10), where singular and plural can look the same. That is why the form mbaazi does not visibly change.

This is also why other words referring to it may use class markers like zi- or zo-, as in:

• mbaazi tulizonunua = the peas that we bought

Tulizonunua can be broken down like this:

• tu- = we
• -li- = past tense
• -zo- = relative marker agreeing with mbaazi
• -nunua = buy

So literally it means something like:

• we-past-which/because-of-class-10-bought

A natural English translation is:

• that we bought
• which we bought

So:

• mbaazi tulizonunua leo = the peas that we bought today

Because it agrees with mbaazi.

In Swahili, when you say the X that..., the that/which part is built into the verb, and it must match the noun class of the noun being described.

Since mbaazi is treated as a plural noun in the N/N class, the relative marker is -zo-.

Compare:

• kitabu nilichonunua = the book that I bought
• vitabu nilivyonunua = the books that I bought
• mbaazi tulizonunua = the peas that we bought

So -zo- is there because the clause refers back to mbaazi.

This is a very important point: the main subject of the sentence is jumla, not mbaazi.

The structure is:

• Jumla ya mbaazi tulizonunua leo = the total amount of peas we bought today

Since jumla is the head noun, the verb must agree with jumla. That is why we get:

• i-natosha = it is enough

If the sentence had started directly with mbaazi as the subject, then you would expect:

• Mbaazi tulizonunua leo zinatosha...
  = The peas we bought today are enough...

So:

• inatosha agrees with jumla
• tulizonunua agrees with mbaazi

Inatosha comes from the verb -tosha, meaning to be enough or to suffice.

It breaks down as:

• i- = subject marker for the noun class of jumla
• -natosha = is enough / suffices

So inatosha means:

• it is enough
• it suffices

Examples:

• Hii inatosha. = This is enough.
• Chakula kinatosha. = The food is enough.
• Jumla ya mbaazi inatosha. = The total amount of peas is enough.

Kwa often means for, to, with, or in terms of, depending on context.

Here, kwa chakula means something like:

• for food
• for a meal / meals
• for use as food

So inatosha kwa chakula cha siku mbili means the amount is enough for food for two days.

In natural English, you might translate the whole idea more smoothly rather than word-for-word.

This phrase means food of two days or more naturally food for two days.

Breakdown:

• chakula = food / meal
• cha = associative connector agreeing with chakula
• siku mbili = two days

So:

• chakula cha siku mbili = food for two days / two days’ worth of food

The connector is cha because chakula belongs to the noun class that takes cha in this pattern.

Compare:

• chai ya asubuhi = morning tea
• chakula cha jioni = evening meal
• nguo za watoto = children’s clothes

In Swahili, siku can mean day or days without changing form. The number tells you whether it is singular or plural.

So:

• siku moja = one day
• siku mbili = two days
• siku tatu = three days

This is normal for some Swahili nouns: the singular and plural look the same.

Leo means today, and here it modifies the buying event:

• tulizonunua leo = that we bought today

This placement is very natural in Swahili. The time word often comes after the verb or verb phrase.

So the relative clause is:

• tulizonunua leo = we bought today

You could think of it as answering which peas?
Answer: the ones we bought today.

Yes, a little.

The Swahili sentence is structured roughly like this:

• Jumla ya mbaazi = the total amount of peas
• tulizonunua leo = that we bought today
• inatosha = is enough
• kwa chakula cha siku mbili = for food for two days

English often uses a similar order, but Swahili packs a lot of information into the verb, especially in relative clauses.

So instead of using a separate word like that, Swahili builds it into the verb:

• tulizonunua = that we bought

That is one of the biggest structural differences learners notice.

Yes. A simpler version might be:

• Mbaazi tulizonunua leo zinatosha kwa siku mbili.

This means roughly:

• The peas we bought today are enough for two days.

That version uses mbaazi directly as the subject, so the verb becomes zinatosha instead of inatosha.

The original sentence with jumla ya sounds a bit more like:

• The total amount of peas we bought today is enough...

So the original is slightly more formal or more precise about the quantity.
