Nimepata asilimia hamsini katika mtihani wa hesabu, lakini nataka zaidi.

Nimepata can be divided into three parts:

• ni- = I
• -me- = a perfect marker, often used for something that has already happened or has been completed
• -pata = get, receive, obtain

So nimepata means I have got, I got, or I have received, depending on context.

In this sentence, it naturally means something like I got or I have scored.

In Swahili, -pata is very commonly used in contexts where English might say score, get, or receive a grade or mark.

So:

• Nimepata asilimia hamsini = I got fifty percent

This is a normal and natural way to talk about exam results in Swahili.

Asilimia means percent and hamsini means fifty.

So:

• asilimia hamsini = fifty percent

Swahili often puts the number after the noun, just as English does here.

You may also see other examples like:

• asilimia kumi = ten percent
• asilimia mia moja = one hundred percent

Katika means in, within, or sometimes on, depending on context.

In this sentence:

• katika mtihani wa hesabu = in the math exam

It introduces the context where the result was obtained.

In everyday Swahili, some speakers might also use kwenye in similar situations, but katika is perfectly correct and slightly more formal or neutral in tone.

The wa links the two nouns and shows a relationship like of in English.

So:

• mtihani wa hesabu = exam of mathematics
• natural English: math exam

This wa is called a genitive connector or possessive connector, and it changes form depending on the noun class of the first noun.

Here:

• mtihani belongs to a noun class that takes wa
• therefore: mtihani wa hesabu

Hesabu literally relates to calculation, arithmetic, or mathematics, and in many learner contexts it is translated simply as math.

So mtihani wa hesabu is a natural way to say math exam.

Depending on context, hisabati may also be used for mathematics, but hesabu is common and understandable.

Lakini means but.

It connects two contrasting ideas:

• Nimepata asilimia hamsini katika mtihani wa hesabu = I got fifty percent in the math exam
• lakini nataka zaidi = but I want more

So it works just like but in English.

In standard Swahili, the first person singular present form is typically:

• ni- = I
• -na- = present / ongoing
• -taka = want

This gives ninataka = I want.

However, in actual usage, ninataka is very commonly contracted to nataka. Both are widely understood, and nataka is extremely common in everyday speech and writing.

So:

• ninataka zaidi
• nataka zaidi

Both mean I want more, but nataka is the more usual shorter form.

Zaidi means more, further, or in greater amount.

In this sentence:

• nataka zaidi = I want more

The exact meaning depends on context. Here it probably means:

• a higher score
• better results
• more than fifty percent

So zaidi does not have to repeat asilimia. The listener understands that more refers to the exam result.

It uses two different time references:

• Nimepata uses the perfect marker -me-, which refers to something already achieved or completed: I got / I have got
• nataka uses the present marker -na-, meaning I want

So the sentence mixes a completed action with a present desire:

• I got fifty percent ... but I want more

Yes. Literally, -pata is a general verb meaning get or obtain, so the phrase could literally be understood as I have obtained fifty percent.

But in the context of an exam, the natural interpretation is:

• I scored fifty percent
• I got fifty percent

So the exam context makes the meaning clear.

Swahili does not usually have a separate word for the or a/an like English does.

So:

• mtihani wa hesabu can mean a math exam or the math exam

The context tells you which one is intended. In this sentence, English would probably translate it as the math exam, but Swahili does not need a separate article.

Yes, in many contexts you could.

• katika mtihani wa hesabu = in the math exam
• kwenye mtihani wa hesabu = in/on the math exam

Both can work, though they may differ slightly in tone or usage depending on region and speaker preference. Katika often sounds a bit more formal or careful, while kwenye is very common in everyday speech.

The sentence follows a very normal Swahili order:

• Nimepata asilimia hamsini = verb + object
• katika mtihani wa hesabu = prepositional phrase giving context
• lakini nataka zaidi = contrasting clause

So the structure is roughly:

• I got fifty percent
• in the math exam
• but I want more

This is close to English word order, which makes the sentence fairly learner-friendly.

No, it sounds completely natural.

The speaker is saying:

• I got fifty percent
• but I am not satisfied
• I want a better result next time

That is a very natural contrast, and lakini nataka zaidi expresses that clearly and simply.
