Mama anaongeza tango kwenye saladi, lakini usiweke siki nyingi kwenye kachumbari.

Because anaongeza breaks down like this:

• a- = he/she
• -na- = present time marker
• -ongeza = add / increase

So anaongeza can mean she is adding or she adds, depending on context. In this sentence, Mama anaongeza... is most naturally understood as Mom is adding...

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

So:

• Mama can mean mother / mom
• tango can mean a cucumber or the cucumber
• saladi can mean salad or the salad

You figure out the exact meaning from context.

Kwenye is a very common locative word meaning something like:

• in
• into
• on
• at

The best English translation depends on the situation.

In this sentence:

• kwenye saladi = into the salad or in the salad
• kwenye kachumbari = into the kachumbari or in the kachumbari

So kwenye is doing the job that English prepositions like in or into would do.

Weka means put as a command.

Usiweke is the negative singular command, meaning don’t put.

It can be broken down like this:

• u- = you singular
• -si- = negative marker
• -weke = subjunctive form of weka

So:

• Weka siki = Put vinegar
• Usiweke siki = Don’t put vinegar

This is a very common pattern in Swahili negative commands.

In negative commands, Swahili usually uses the subjunctive ending -e instead of the normal final -a.

So:

• base verb: weka
• negative command form: usiweke

This happens with many verbs:

• fanya → usifanye = don’t do
• soma → usisome = don’t read
• weka → usiweke = don’t put

So the -e ending is a normal grammar feature here.

It is speaking to one person.

• usiweke = don’t put to one person
• msiweke = don’t put to more than one person

So this sentence is giving a warning or instruction to a single person.

This is because adjectives in Swahili must agree with the noun class of the noun they describe.

Siki belongs to the noun class that takes agreement like nyingi.

So:

• siki nyingi = a lot of vinegar / much vinegar

Even though English uses much with an uncountable noun, Swahili still uses its normal adjective agreement system. So the important thing is noun class agreement, not whether English would say many or much.

In natural English, it means much here:

• usiweke siki nyingi = don’t put too much vinegar

But the Swahili form is still nyingi because of noun class agreement. So you should not try to match it word-for-word with English many vs much.

Tango means cucumber.

So:

• Mama anaongeza tango kwenye saladi = Mom is adding cucumber to the salad

A learner might expect a plural, but Swahili often leaves number to context. Here tango can be understood as cucumber in a general sense, or a cucumber.

Kachumbari is a common East African dish, usually a fresh mixture of chopped vegetables such as:

• tomatoes
• onions
• chili
• sometimes cucumber or other ingredients

It is often like a fresh relish or salad. So while English might just say salad in some contexts, kachumbari refers to a more specific kind of dish.

Not exactly.

• saladi is a more general word for salad
• kachumbari is a specific East African salad/relish

So the sentence contrasts two different dishes:

• cucumber is being added to the salad
• but too much vinegar should not be added to the kachumbari

Lakini means but.

It connects the two parts of the sentence:

• Mama anaongeza tango kwenye saladi
• lakini usiweke siki nyingi kwenye kachumbari

So the structure is:

statement + lakini + command

That is very normal in Swahili.

Mama can mean different things depending on context, including:

• mom
• mother
• a mother
• sometimes a respectful way to refer to a woman

In this sentence, Mom or Mother is the most natural interpretation.

Yes. The word order is very natural.

The first clause is:

• Mama = subject
• anaongeza = verb
• tango = object
• kwenye saladi = location/destination

The second clause is:

• usiweke = negative command
• siki nyingi = object
• kwenye kachumbari = location/destination

So the sentence follows a very common Swahili pattern: subject + verb + object + location, and then a second clause after lakini.

Yes. Both can work.

Swahili kwenye does not always force the same distinction English makes between in and into. So depending on context:

• anaongeza tango kwenye saladi can be adds cucumber to the salad
• or adds cucumber into the salad
• or even adds cucumber in the salad

In good English, to the salad is usually the most natural translation of the first part.

The first half is a statement, and the second half is a negative command.

• Mama anaongeza... = statement about what someone is doing
• usiweke... = instruction telling someone what not to do

So the sentence combines description and advice/instruction in one line.
