Tafadhali leta ungo; nataka kupepeta unga kabla ya kupika chapati.

Both nataka and ninataka mean I want.

• ninataka is the full form
• nataka is a very common shortened form

The full structure is:

• ni- = I
• -na- = present tense
• -taka = want

So learners often first see ninataka, but in real life nataka is extremely common and completely normal.

Leta is the imperative form of -leta, meaning bring.

In this sentence, it is a command/request to one person:

• leta = bring

If you were speaking to more than one person, you would usually say:

• leteni = bring (you all)

Because the sentence also has tafadhali, it sounds like a polite request rather than a harsh order.

Tafadhali means please.

It softens the command leta ungo and makes it polite. Swahili often uses tafadhali the same way English uses please in requests.

So:

• Leta ungo = direct
• Tafadhali leta ungo = polite

The ku- marks the infinitive, which is the to ... form of the verb.

So:

• pepeta = sift! / sift
• kupepeta = to sift

After a verb like nataka (I want), Swahili normally uses the infinitive:

• nataka kupepeta = I want to sift

The same thing happens later with kupika:

• kupika = to cook / to prepare

These are two different words:

• ungo = sieve
• unga = flour

They look very similar, so they are easy to mix up. Only the final vowel changes:

• u-n-go
• u-n-ga

This is a good pair to memorize carefully because both are common in kitchen vocabulary.

In both words, ng is pronounced with a hard g sound, like the ngg in finger, not like the ng in sing.

So roughly:

• ungo ≈ oon-go
• unga ≈ oon-ga

That is because Swahili ng and ng' are different:

• ng = like finger
• ng' = like sing

Since these words have ng without an apostrophe, keep the hard g.

Kabla ya is a set expression meaning before when followed by a noun or an infinitive phrase.

So:

• kabla ya kupika = before cooking / before preparing
• kabla ya kwenda = before going
• kabla ya chakula = before food / before the meal

You should usually learn kabla ya as one unit here. The ya is not optional in this pattern.

Swahili generally does not use articles like English a, an, or the.

So:

• ungo can mean a sieve or the sieve
• unga can mean flour or the flour
• chapati can mean chapati or the chapati

The exact meaning depends on context, not on a separate article word.

Chapati is a loanword, and in Swahili it is often used with the same form for both singular and plural.

So context tells you whether one chapati or several are meant.

In this sentence, chapati is probably being used in a general food sense, so the speaker means preparing chapati as a dish rather than focusing on the number.

It can cover both ideas.

The verb -pika is a broad cooking verb. Depending on context, English may translate it as:

• cook
• make
• prepare

So kupika chapati is natural Swahili. In English, you might choose make chapati or cook chapati, depending on what sounds best in the situation.

Yes. The word order is very natural.

Swahili commonly uses:

• verb + object

So here you get:

• leta ungo
• kupepeta unga
• kupika chapati

The sentence first gives the request, then gives the reason:

• polite request
• explanation of why the speaker wants it

That flow is very normal in Swahili.

Not really, because tafadhali makes it polite.

Without tafadhali, leta ungo could sound more like a straightforward command. With tafadhali, it sounds like a normal polite request.

If you wanted to make it even softer, you could use a question form, for example:

• Tafadhali, unaweza kuleta ungo? = Please, can you bring a sieve?

But the original sentence is already polite and natural.
