Sipendi uongo darasani.

Because it is built from the verb -penda (to like / to love) plus negative subject marking.

Breakdown:

• si- = I do not
• -pend- = verb root like/love
• -i = the final vowel used in many present negative forms

So:

• ninapenda = I like
• sipendi = I do not like

In Swahili, the negative present often changes the verb’s final -a to -i.

It is inside the verb sipendi.

Swahili usually does not need a separate subject pronoun if the verb already shows the subject. Here, si- tells you the subject is I in a negative statement.

You could say Mimi sipendi uongo darasani for emphasis, but mimi is not necessary.

uongo means lie, falsehood, dishonesty, or lying.

In this sentence, it can be understood in a general sense:

• I don't like lies in the classroom
• I don't like lying in class
• I don't like dishonesty in the classroom

The exact English wording depends on context.

Because uongo often works like an abstract or general noun, similar to lying or falsehood in English.

So Swahili does not have to mark it as plural to express a general idea. The sentence is talking about lying/dishonesty in general, not necessarily a specific number of individual lies.

darasa means class, lesson, or classroom.
The ending -ni is a locative ending, often meaning in, at, or to a place.

So:

• darasa = class / classroom
• darasani = in class / in the classroom

This is a very common pattern in Swahili:

• nyumba = house
• nyumbani = at home / in the house

It can mean either one, depending on context.

Swahili often uses one expression where English might choose between:

• in class
• in the classroom
• sometimes even during lessons

So Sipendi uongo darasani could refer to behavior during class, not only the physical room.

Swahili does not use articles like English a/an and the.

That means nouns often appear without a separate word for definiteness:

• uongo can mean a lie, lies, lying, or falsehood
• darasani can mean in class or in the classroom

Context tells you the most natural interpretation.

This is the normal, neutral order:

• sipendi = I don't like
• uongo = lies / lying
• darasani = in class

So the sentence is structured like:

verb + object + location

Swahili word order can be somewhat flexible, but this version sounds natural and straightforward.

Yes. -penda can mean both like and love.

For example:

• Nakupenda can mean I love you
• In everyday contexts, -penda can also simply mean like

In this sentence, like is the better English choice:

• I don't like lies in class rather than
• I don't love lies in class

The positive version is:

Ninapenda uongo darasani.

Breakdown:

• ni- = I
• -na- = present tense
• penda = like

So:

• ninapenda = I like
• sipendi = I do not like

A useful approximation is:

oo-ONG-go

A few pronunciation notes:

• uo is pronounced as two vowels together
• ng in uongo is pronounced like the ng in finger, not like the ng in sing
• stress in Swahili usually falls on the second-to-last syllable, so the stress is on ONG

So uongo sounds roughly like oo-ON-go.
