Watoto walifurahi kumwona twiga akila majani.

Watoto is the plural of mtoto, which means child.

This is part of a very common human noun pattern in Swahili:

• mtoto = child
• watoto = children

The change from m- to wa- is a noun-class change from singular to plural. That same plural class also affects the verb, which is why the sentence has wa- in walifurahi.

Walifurahi can be broken down like this:

• wa- = they (for class 2, used with plural humans like watoto)
• -li- = past tense
• furahi = be happy / rejoice / be glad

So walifurahi means they were happy or they became happy/glad.

Swahili often packs subject and tense into one verb word, unlike English.

Swahili normally does not use articles like a, an, or the.

So:

• watoto can mean children or the children
• twiga can mean a giraffe or the giraffe
• majani can mean leaves or the leaves

The exact meaning depends on context. That is very normal in Swahili.

Kumwona means to see him/her/it or, in this sentence, to see the giraffe.

It breaks down like this:

• ku- = to (infinitive marker)
• mw- = object marker for a singular animate being
• -ona = see

So:

• kuona = to see
• kumwona = to see him/her/it

In this sentence, the object marker refers to twiga. Swahili often uses an object marker even when the noun itself is also said, especially with specific animate objects.

Because twiga refers to a living creature, and animate nouns in Swahili often take animate agreement, even if their noun form does not look like a typical class 1/2 noun.

So the giraffe is treated grammatically like a singular animate being here:

• object marker: mw- in kumwona
• subject marker: a- in akila

That is why the sentence does not use a non-animate agreement marker there.

Twiga can be either singular or plural in form. The word itself often stays the same.

In this sentence, it is clearly singular because of the agreement:

• kumwona = to see it/him/her (singular)
• akila = while it/he/she was eating (singular)

If it were plural, you would expect plural agreement, for example something like:

• kuwaona twiga wakila majani = to see giraffes eating leaves

Akila means while eating or as it was eating.

It breaks down like this:

• a- = singular animate subject
• -ki- = while / in the process of
• -la = eat

So akila majani means while eating leaves.

This -ki- form is used to show an action happening at the same time as another action. Here, it describes what the giraffe was doing when the children saw it.

By contrast:

• anakula = it is eating
• akila = while it is/was eating

So akila is the better form for linking the giraffe’s action to the seeing.

The core verb root is -la = eat.

The ku- in kula is the infinitive marker, so:

• kula = to eat

With some verb forms, especially with very short verb roots like -la, extra material appears or disappears depending on the construction. That is why learners see forms like:

• kula = to eat
• anakula = he/she/it is eating
• alikula = he/she/it ate
• akila = while he/she/it was eating
• ale = let him/her eat / that he/she eat

So yes, it is the same verb, just in different grammatical forms.

Majani is the plural of jani:

• jani = leaf
• majani = leaves

In real usage, majani can also refer more generally to foliage, green leaves, or sometimes vegetation, depending on context. In this sentence, leaves is the most natural meaning because a giraffe is eating them.

The sentence has three main parts:

1. Watoto walifurahi
   = The children were happy

2. kumwona twiga
   = to see the giraffe

3. akila majani
   = while it was eating leaves

So the whole sentence is structured like:

• main clause
  • infinitive complement
    • descriptive action happening at the same time

A natural English understanding is:

• The children were happy to see the giraffe eating leaves
• or The children were happy when they saw a giraffe eating leaves

The important thing is that akila majani describes twiga, not watoto. The giraffe is the one eating the leaves.
