Matumizi ya kila mwezi ni mengi.

Here matumizi means expenses, expenditure, or sometimes usage/consumption, depending on context.

Grammatically, matumizi belongs to noun class 6, which often contains plural or mass nouns. In this sentence, it is being treated as a plural/collective noun, which is why later words agree with it as class 6.

So even though English may say expenses or spending, Swahili uses matumizi as the noun.

ya is the linking word that connects matumizi with kila mwezi.

So:

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

Together, matumizi ya kila mwezi means monthly expenses.

The word ya is not random: it agrees with matumizi in its noun class. With class 6 nouns, this connector is ya.

Literally, kila mwezi means every month:

• kila = every / each
• mwezi = month

But when attached to a noun with ya, it often works like the English adjective monthly.

So:

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

This is a very normal Swahili way to express something that happens regularly each month.

Because mengi agrees with matumizi.

The adjective stem here is -ingi, meaning many / much / a lot. In Swahili, adjectives must agree with the noun class of the noun they describe.

Since matumizi is class 6, -ingi becomes mengi.

Examples of agreement with -ingi:

• class 1/2: wengi
• class 3/4: mingi
• class 5/6: mengi
• class 7/8: vingi

So:

• matumizi ni mengi = the expenses are many / a lot / high

Good question. In English, we often say:

• expenses are high
• costs are high

In Swahili, saying matumizi ni mengi is very natural and means that the expenses are a lot or high.

So mengi does not always have to be translated literally as many. In context, it can mean:

• numerous
• a lot
• substantial
• high

A more natural English translation may be Monthly expenses are high, even though the Swahili literally says something closer to Monthly expenses are many/a lot.

ni is the copula, meaning is/are.

So:

• Matumizi ya kila mwezi = monthly expenses
• ni mengi = are many / are a lot / are high

Together:

• Matumizi ya kila mwezi ni mengi.
• Monthly expenses are high.

In many Swahili sentences with adjectives or descriptions, ni links the subject to what is being said about it.

Yes. That is often a more natural English translation.

Because matumizi can mean expenses, spending, consumption, or usage, the best translation depends on context.

Possible translations include:

• Monthly expenses are high.
• Monthly spending is a lot.
• There are many monthly expenses.

If the context is personal finance, Monthly expenses are high is probably the best translation.

In practice, matumizi is usually used as it is, especially for meanings like use, usage, consumption, or expenses.

It comes from the verb -tumia (to use, to spend).

Learners often expect a clear singular-plural pair like in English, but here it is better to learn matumizi as a common noun used collectively.

So for this sentence, you do not need to look for a singular form; just treat matumizi as the normal word for expenses/spending/usage.

Yes. Matumizi is a flexible word.

Depending on context, it can mean:

• use
• usage
• consumption
• spending
• expenses

For example:

• in finance: expenses / spending
• in electricity or water: consumption / usage
• in general: use

So this sentence could mean different things in different contexts, but if the meaning shown to the learner is about money, then monthly expenses is the right interpretation.

Yes, that is possible, but it is slightly different in nuance.

• ya kila mwezi = monthly, every month, regular monthly
• ya mwezi = of the month or for the month

So:

• Matumizi ya kila mwezi ni mengi suggests regular monthly expenses in general.
• Matumizi ya mwezi ni mengi can sound more like the expenses for the month are a lot.

The original sentence is a better choice when talking about recurring monthly expenses.

A simple pronunciation guide:

• Matumizi = ma-tu-MI-zi
• ya = ya
• kila = KI-la
• mwezi = MWE-zi
• ni = ni
• mengi = ME-ngi

Swahili usually stresses the second-to-last syllable of a word, which is why you get:

• ma-tu-MI-zi
• KI-la
• MWE-zi
• ME-ngi

Also, Swahili pronunciation is generally quite regular, so words are usually pronounced close to how they are spelled.
