Mimi sipendi sharubati hii kwa sababu ni chungu sana.

Yes. Sipendi already includes the subject I.

• si- = I do not
• -penda = like / love

So mimi is not required for basic grammar. It is often added for:

• emphasis: I don’t like this syrup...
• contrast: Maybe other people like it, but I do not.
• clarity in conversation

So the sentence could also be:

Sipendi sharubati hii kwa sababu ni chungu sana.

That would still be correct.

Sipendi breaks down like this:

• si- = negative subject marker for I
• -pend- = the verb root like / love
• -i = the final vowel used here in the negative form

So:

• napenda = I like
• sipendi = I do not like

This is a very common pattern in Swahili. In the present negative, the verb often ends in -i instead of -a.

In Swahili, the negative subject marker changes depending on the person.

For the verb kupenda in the present:

• napenda = I like
• sipendi = I do not like

Other persons look different:

• hupendi = you do not like
• hapendi = he/she does not like
• hatupendi = we do not like
• hamupendi = you all do not like
• hawapendi = they do not like

So si- specifically marks first person singular negative in this kind of sentence.

Sharubati usually refers to a sweet drink, syrup, sherbet-like drink, or flavored beverage, depending on context and region.

It is a loanword, and in real usage the exact English translation can vary:

• syrup
• sherbet drink
• sweet beverage
• sometimes just juice/drink, depending on context

So in this sentence, the important point is simply that it is a drink the speaker is talking about.

In Swahili, demonstratives like this usually come after the noun.

So:

• sharubati hii = this syrup/drink
• literally: syrup this

This noun + demonstrative order is normal in Swahili.

A learner coming from English often expects this syrup, but Swahili usually says the equivalent of syrup this.

Hii means this.

Its form depends on the noun class of the noun it refers to.
Here, sharubati takes the same demonstrative pattern as nouns in the N-class, so the correct form is hii.

Compare:

• kitabu hiki = this book
• mtoto huyu = this child
• sharubati hii = this syrup/drink

So you cannot just use one single word for this with every noun. The demonstrative must agree with the noun class.

Kwa sababu means because.

It introduces a reason:

• Sipendi sharubati hii kwa sababu ni chungu sana. = I don’t like this syrup because it is very bitter.

It is a very common and useful expression in Swahili.

You can think of it as a fixed phrase meaning because / for the reason that.

In English, you must say it is very bitter.
In Swahili, the subject can sometimes be left understood from context, especially when it is obvious what is being described.

So:

• ni chungu sana = it is very bitter / it’s very bitter

Here, the listener understands that sharubati hii is what is bitter.

Swahili often allows this kind of omission when the meaning is clear.

Here ni works like is / be in English.

So:

• ni chungu = it is bitter
• ni chungu sana = it is very bitter

This is a very common way to link a subject to a description in Swahili.

Even though English uses different forms like am, is, are, Swahili often uses ni in this kind of equational or descriptive sentence.

Here chungu means bitter.

So:

• ni chungu sana = it is very bitter

Be aware that chungu can have related meanings in some contexts, and some learners may confuse it with other taste words. For taste, common words include:

• tamu = sweet
• chungu = bitter
• chachu = sour
• chumvi = salty

In this sentence, the meaning is clearly about taste.

Sana means very.

It usually comes after the adjective or verb it intensifies:

• chungu sana = very bitter
• nzuri sana = very good
• napenda sana = I like very much / I really like

So ni chungu sana literally follows the normal Swahili pattern: is bitter very.

Mostly it is quite similar, but there are a few important differences.

Sentence structure:

• Mimi = I
• sipendi = do not like
• sharubati hii = this syrup/drink
• kwa sababu = because
• ni chungu sana = it is very bitter

A natural word-for-word feeling would be:

I do-not-like syrup this because is bitter very.

The biggest differences for an English speaker are:

1. this comes after the noun: sharubati hii
2. very comes after the adjective: chungu sana
3. the subject it can be omitted in the second clause when understood

Yes, absolutely.

In fact, Sipendi sharubati hii kwa sababu ni chungu sana may sound more neutral in many contexts.

Use mimi when you want:

• emphasis
• contrast
• extra clarity

So both are correct:

• Mimi sipendi sharubati hii kwa sababu ni chungu sana.
• Sipendi sharubati hii kwa sababu ni chungu sana.

The version with mimi is just a bit more emphatic.

Grammatically, kupenda can cover both like and love, depending on context. But in a sentence about taste, like is the more natural translation.

So here:

• sipendi sharubati hii is best understood as I don’t like this syrup/drink

Using love in English would sound too strong in this context unless the speaker is being dramatic.

You would change the verb from negative to positive:

• Napenda sharubati hii. = I like this syrup.

Compare:

• napenda = I like
• sipendi = I do not like

If you want to keep the reason clause:

• Napenda sharubati hii kwa sababu ni tamu sana. = I like this syrup because it is very sweet.

This is a useful contrast for learning both the positive and negative forms.
