Si kwamba sarufi hii ni rahisi sana, bali tukifanya mazoezi kila siku tutaielewa.

Si kwamba is a very common way to say It’s not that... or It is not as if... in Swahili.

In this sentence, it introduces a correction or clarification:

• Si kwamba sarufi hii ni rahisi sana...
• It’s not that this grammar is very easy...

So the speaker is not denying grammar itself exists or anything like that. They are softening the statement and then giving the real point in the second half of the sentence.

Sarufi belongs to noun class 9 in Swahili, and the demonstrative used with class 9 singular nouns is hii.

So:

• sarufi hii = this grammar

This is the same pattern you see with other class 9 nouns:

• nyumba hii = this house
• barua hii = this letter
• nguo hii = this clothing/garment

Even though sarufi does not visibly change its form, it still controls agreement like a class 9 noun.

The word ni here is the copula, meaning is/are.

So:

• sarufi hii ni rahisi sana
• literally: this grammar is very easy

In Swahili, when linking a subject with a description or identity, ni is often used:

• Yeye ni mwalimu = He/she is a teacher
• Kitabu hiki ni kizuri = This book is good
• Sarufi hii ni rahisi = This grammar is easy

So ni is doing the job that is does in English.

In Swahili, sana usually comes after the word it intensifies.

So:

• rahisi sana = very easy
• literally: easy very

This is normal Swahili word order. A few similar examples:

• nzuri sana = very good
• ngumu sana = very difficult
• haraka sana = very quickly / very fast

So even though English says very easy, Swahili says easy very.

Bali means something like but rather, instead, or on the contrary. It often follows a negative idea and introduces the real or corrected idea.

In this sentence:

• Si kwamba ... , bali ...
• It’s not that ... , but rather ...

So the sentence contrasts two ideas:

1. not that the grammar is very easy
2. rather, if we practice every day, we will understand it

Lakini also means but, but bali often sounds more precise in this kind of correction structure.

Compare:

• Si kwamba nina pesa, bali nina mpango mzuri.
• It’s not that I have money, but rather I have a good plan.

That is the same pattern as your sentence.

Tukifanya breaks down like this:

• tu- = we
• -ki- = if/when/while
• -fanya = do

So:

• tu-ki-fanya
• if/when we do

Because mazoezi means practice or exercises, the whole phrase:

• tukifanya mazoezi
• means if we practice or more literally if we do practice/exercises

This -ki- form is very common in Swahili.

Examples:

• ukisoma = if/when you read
• nikija = if/when I come
• tukijifunza = if/when we learn

It can potentially mean any of those depending on context, because -ki- is flexible.

Common meanings of the -ki- form include:

• if
• when
• while

In this sentence, the most natural meaning is:

• if we practice every day, we will understand it

That is because the second verb is in the future:

• tutaielewa = we will understand it

So the sentence gives a condition leading to a result. English usually expresses that as if.

Mazoezi literally can mean exercises or practice. In many contexts, Swahili uses kufanya mazoezi for to practice or to do exercises.

So:

• kufanya mazoezi = to practice
• tukifanya mazoezi = if we practice

This is broader than just physical exercise. It can also be used for language learning, music, skills, and training.

Examples:

• Ninafanya mazoezi ya Kiswahili = I am practicing Swahili
• Fanya mazoezi kila siku = Practice every day

So in your sentence, mazoezi is not only about physical exercise. It means regular practice.

Tutaielewa breaks down into:

• tu- = we
• -ta- = future
• -i- = it
• -elewa = understand

So:

• tu-ta-i-elewa
• we will understand it

This is a very typical Swahili verb structure:

subject marker + tense marker + object marker + verb root

For example:

• nitakupenda = I will love you
• watakisoma = they will read them
• tutaielewa = we will understand it

The -i- is the object marker for the noun sarufi.

Since sarufi is a class 9 noun, the object marker used for it is i-.

So:

• sarufi hii = this grammar
• tutaielewa = we will understand it

The it is not stated again as a separate word, because Swahili often puts the object inside the verb.

So the sentence does not need to repeat sarufi in the second half. The verb already shows what is being understood.

Because Swahili often uses an object marker in the verb instead of repeating the noun.

Instead of saying something like:

• ... tutaelewa sarufi hii

the sentence says:

• ... tutaielewa

Both can work, but tutaielewa is smooth and natural because the -i- already stands for sarufi hii.

This is one of the big differences from English. English usually needs a separate word like it, but Swahili can build that idea directly into the verb.

Yes. The pattern is very natural:

• Si kwamba ... bali ...

It is used when a speaker wants to reject one interpretation and replace it with the real point.

So the sentence structure is basically:

• Not that X, but rather Y.

In your sentence:

• Not that this grammar is very easy, but rather, if we practice every day, we will understand it.

This is a useful pattern to learn because it sounds natural and thoughtful in conversation and writing.
