Kulea watoto kunahitaji subira na upendo.

Kulea is the infinitive form of the verb -lea, meaning to raise, bring up, or care for. In this sentence, the infinitive is being used like a noun, similar to English raising in Raising children requires patience and love.

So:

• ku- = infinitive marker, like to
• -lea = raise / bring up

Together, kulea can mean either to raise or raising, depending on context.

Because in Swahili, an infinitive phrase can act as the subject of the sentence.

Here, kulea watoto means raising children, and that whole phrase is the subject. After that, the sentence says what is true about that activity:

• kulea watoto = raising children
• kunahitaji subira na upendo = requires patience and love

So the structure is very similar to English:

• Raising children
  • requires patience and love

That ku- is not the infinitive marker here. It is the subject agreement prefix.

The subject of the sentence is kulea watoto, an infinitive phrase. In Swahili, infinitives used as nouns are usually treated as belonging to noun class 15, whose agreement prefix is ku-.

So kunahitaji breaks down like this:

• ku- = subject agreement for the infinitive idea
• -na- = present tense
• -hitaji = need / require

So kunahitaji literally means something like it requires or it needs, where it refers to raising children.

-na- is the usual present-tense marker in Swahili.

So:

• kunahitaji = it requires / it needs

Even though English uses the simple present here, Swahili commonly uses -na- for general present statements too, not only for actions happening right now.

So this sentence is a normal way to express a general truth.

Because watoto is the plural of mtoto.

• mtoto = child
• watoto = children

This follows a very common human noun pattern in Swahili:

• singular: m-
• plural: wa-

So a learner will see many pairs like this:

• mtu / watu = person / people
• mtoto / watoto = child / children

Because the object is already stated explicitly as watoto.

So kulea watoto simply means to raise children. Swahili does not require an object marker when the object noun is present.

You may sometimes see object markers with animate or definite objects in other contexts, but here the plain form kulea watoto is the most straightforward and natural wording.

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

So:

• watoto can mean children, the children, or some children, depending on context
• subira can mean patience
• upendo can mean love

In this sentence, the meaning is general, so English naturally translates it without articles too: Raising children requires patience and love.

Subira means patience.

It is an abstract noun, so it works a lot like English patience: not usually something you count as individual items.

In this sentence, it means the quality of being calm, enduring, and tolerant while raising children.

Upendo means love or affection.

Like subira, it is an abstract noun. Here it refers to the caring, warmth, and affection needed in bringing up children.

So subira na upendo means patience and love as qualities, not specific separate objects.

Here, na means and.

It is connecting two nouns:

• subira
• upendo

So:

• subira na upendo = patience and love

The same word na can also mean with in other sentences, so context tells you which meaning is intended.

No. Kulea is broader than just what biological parents do.

It can refer to:

• raising children
• bringing them up
• caring for them over time
• nurturing them

So it can be used for parents, guardians, relatives, or anyone in a child-rearing role, depending on context.

Yes. A common alternative is:

Malezi ya watoto yanahitaji subira na upendo.

That also means The raising/upbringing of children requires patience and love.

The difference is that:

• kulea watoto uses a verb-based expression: raising children
• malezi ya watoto uses a more noun-based expression: the upbringing/raising of children

Both are correct, but the original sentence is very natural and direct.
