Nataka ujifunze upole ili uepuke kuwasumbua watu wengine bila sababu.

Because the sentence means I want you to learn..., not I want to learn...

In Swahili, after a verb of wanting like nataka, you often use the subjunctive when you want someone else to do something:

• Nataka ujifunze = I want you to learn
• Nataka kujifunza = I want to learn

So ujifunze shows that the speaker is talking about your action, not their own.

Ujifunze can be broken down like this:

• u- = you (singular subject prefix)
• -ji- = reflexive element, often understood as yourself
• -funz- = verb root related to teaching/learning
• -e = subjunctive ending

So kujifunza is the dictionary form, meaning to learn / to study.

A helpful comparison is:

• kufunza = to teach
• kujifunza = to learn

Historically, it is like to teach oneself, though in modern Swahili you usually just learn kujifunza as the normal verb for to learn.

That -e is the usual ending of the subjunctive in Swahili.

The subjunctive is commonly used after expressions of:

• desire
• purpose
• requests
• necessity

In this sentence, it appears twice:

• Nataka ujifunze... = I want you to learn...
• ili uepuke... = so that you may avoid...

So the -e ending is a big clue that the verb is in the subjunctive.

Upole is a noun meaning something like:

• gentleness
• calmness
• softness
• politeness
• mildness

The exact English word depends on context.

In this sentence, it suggests learning a gentle or considerate way of behaving.

It is related to pole, a very common Swahili word associated with softness, gentleness, sympathy, or slowness depending on context.

Because kujifunza can take a direct object.

So:

• kujifunza upole = to learn gentleness / to learn politeness

Swahili does not need a preposition here. English might sometimes say learn gentleness or learn to be gentle, but Swahili can simply use the noun directly after the verb.

Ili means:

• so that
• in order that

It introduces a purpose clause.

So this part:

• ili uepuke kuwasumbua watu wengine bila sababu

means:

• so that you avoid bothering other people for no reason

A very common pattern in Swahili is:

• ili + subjunctive verb

Uepuke breaks down like this:

• u- = you (singular)
• -epuk- = avoid
• -e = subjunctive ending

Dictionary form:

• kuepuka = to avoid

So uepuke means that you avoid / so that you avoid.

Again, it is subjunctive because it follows ili.

Kuwasumbua contains an object marker:

• ku- = infinitive marker (to)
• -wa- = them
• -sumbua = bother / disturb / inconvenience

So:

• kuwasumbua watu wengine = to bother them, namely other people

The -wa- refers to watu wengine.

With human objects, Swahili often likes to include this object marker, especially when the object is specific or clearly identifiable. You may also hear kusumbua watu wengine in some contexts, but kuwasumbua watu wengine is very natural.

• watu = people
• wengine = other

So watu wengine = other people

The form wengine agrees with the noun class of watu.

Compare:

• mtu mwingine = another person / a different person
• watu wengine = other people

So the change from mwingine to wengine is due to noun class agreement.

Bila sababu means:

• without reason
• for no reason
• without a good reason

Breakdown:

• bila = without
• sababu = reason

A useful contrast is:

• bila sababu = without reason
• kwa sababu = because / because of

Those two expressions are easy to confuse, so it is worth memorizing them separately.

It is talking to one person, because the verbs use the singular u- subject marker:

• ujifunze
• uepuke

If you were speaking to more than one person, you would normally use plural forms such as:

• Nataka mjifunze upole ili muepuke kuwasumbua watu wengine bila sababu.

So:

• u- = you singular
• m- / mu- = you plural

A fairly literal version would be:

• I want that you learn gentleness so that you avoid bothering other people without reason.

That is not the most natural English, but it helps show the structure.

More natural English would be something like:

• I want you to learn gentleness so that you avoid bothering other people for no reason.
• I want you to learn to be gentle so that you do not disturb other people unnecessarily.

So when reading Swahili, it often helps to understand both the literal structure and the natural English meaning.
