Matumizi ya kila mwezi yana gharama za lazima.

Here, matumizi means expenses, spending, or expenditure.

The word can also mean use or usage in other contexts, but in this sentence it is clearly about money because it is followed by gharama and described as ya kila mwezi.

So in this sentence, matumizi is best understood as monthly expenses or monthly spending.

Ya kila mwezi means monthly or more literally of every month.

Breakdown:

• ya = of
• kila = every
• mwezi = month

So:

• matumizi ya kila mwezi = expenses of every month = monthly expenses

This is a very common Swahili way to express an adjective-like idea. Instead of one single word like monthly, Swahili often uses a phrase such as of every month.

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

In Swahili, this connector changes to match the noun class of the noun before it. Since matumizi belongs to the ma-/ya- agreement pattern, the connector is ya.

So:

• matumizi ya kila mwezi = expenses of every month

It is not random; it agrees with matumizi.

Yana agrees with matumizi.

The verb -na means to have, and the subject prefix must match the noun class of the subject:

• matumizi takes the class agreement ya-
• therefore ya + na becomes yana

So:

• matumizi yana gharama... = the expenses have costs...

Even though that sounds slightly unusual word-for-word in English, the grammar is normal in Swahili.

Gharama means cost, expense, or price, depending on context.

In many cases, gharama looks the same in singular and plural. It belongs to a noun class where the form often does not change between singular and plural.

So in this sentence, gharama can be understood as:

• costs
• expenses
• charges

The exact English wording depends on context.

Za is another associative connector, like of. It agrees with gharama.

So:

• gharama za lazima literally means costs of necessity
• more naturally in English: necessary costs or essential expenses

This is a very common Swahili structure:

• noun + connector + descriptive noun/expression

So instead of a simple adjective, Swahili often uses a phrase like this.

Not exactly in the same way English uses adjectives.

Lazima often means:

• necessary
• required
• must

In this sentence, za lazima literally means something like of necessity or required ones, which English would usually translate as necessary or essential.

So although it functions like an adjective in translation, its Swahili structure is a little different.

A very literal translation is:

Monthly expenses have necessary costs.

But more natural English could be:

• Monthly expenses include essential costs.
• Monthly spending includes necessary expenses.
• There are essential costs in monthly expenses.

The best choice depends on the wider context, but the key idea is that the sentence is talking about monthly expenses and essential/necessary costs.

That is a good question, because to an English speaker the sentence can feel slightly overlapping in meaning.

• matumizi = spending, expenditure, expenses
• gharama = costs, charges, expenses

Swahili sometimes allows this kind of wording where the general category is stated first and then a more specific type within it. So the sentence is basically highlighting that within monthly spending, there are costs that are necessary or unavoidable.

Depending on context, it may be emphasizing essential budget items.

Usually, Swahili prefers the phrase ya kila mwezi for monthly in many contexts.

So:

• matumizi ya kila mwezi = monthly expenses
• malipo ya kila mwezi = monthly payments

This pattern is very normal and often more idiomatic than trying to force a one-word adjective.

The structure is:

• Matumizi ya kila mwezi = subject noun phrase
• yana = verb, have
• gharama za lazima = object noun phrase

So the sentence is built like:

[Subject] + [verb] + [object]

More literally:

Monthly expenses + have + necessary costs

This is a useful sentence for seeing how Swahili links nouns together using agreement words like ya and za.
