Mtoto anaogopa mdudu huyo.

A simple breakdown is:

• Mtoto = child
• anaogopa = is afraid of / fears
• mdudu = bug / insect
• huyo = that (agreeing with the noun class of mdudu)

So the sentence structure is basically:

• Mtoto → subject
• anaogopa → verb
• mdudu huyo → object phrase, that bug/insect

No. Mtoto just means child, without specifying gender.

Like many Swahili nouns, it is not grammatically marked for male vs. female in the way English sometimes is. So depending on context, it could mean:

• the boy
• the girl
• the child

The verb form a- in anaogopa also just means he/she for a singular human subject.

Anaogopa can be broken into parts:

• a- = he/she
• -na- = present tense / ongoing present
• -ogopa = verb stem meaning fear / be afraid of

So:

• a + na + ogopa → anaogopa

A very natural English translation is he/she is afraid of.

It can mean either, depending on how natural you want the English to sound.

• Mtoto anaogopa mdudu huyo = The child is afraid of that bug
• also possible: The child fears that bug

In normal English, is afraid of is usually the more natural translation here.

In Swahili, demonstratives like this and that usually come after the noun, not before it.

So:

• mdudu huyo = that bug
• literally closer to bug that

This is normal Swahili word order. English says that bug, but Swahili says bug that.

Swahili has different demonstrative forms that depend on both:

1. the noun class
2. the distance or discourse meaning

For this noun class, the common forms are:

• huyu = this
• huyo = that
• yule = that over there / that one farther away

So mdudu huyo means that bug.

In many learning contexts, huyo is the standard choice for that. It can also refer to something already mentioned in the conversation, not just physical distance.

Because Swahili uses noun classes, and words connected to a noun often have to agree with that noun’s class.

Mdudu belongs to the singular m-/wa- class here, so the demonstrative must use the matching form:

• singular: mdudu huyo
• plural: wadudu hao

This agreement is a very important part of Swahili grammar. It is similar in idea to how some languages make adjectives or articles match the noun.

That is a very common learner question, because English speakers often expect the m-/wa- class to be only for people.

But in Swahili, this class also includes many living beings, not just humans. So mdudu is singular, and its plural is:

• mdudu = bug/insect
• wadudu = bugs/insects

Because it is singular in that class, related agreement can look like human agreement too.

Swahili does not usually have separate articles like English a/an and the.

That means a noun like mdudu can mean:

• a bug
• the bug

The exact meaning depends on context.

In this sentence, huyo makes the noun specific, so mdudu huyo is naturally understood as that bug.

Yes, that is a useful thing to notice.

The sentence you have is:

• Mtoto anaogopa mdudu huyo

This is perfectly good Swahili.

But because mdudu huyo is a specific animate noun, some speakers may also use an object marker:

• Mtoto anamwogopa mdudu huyo

Here -mw- refers to the object mdudu huyo.

Very broadly:

• without object marker: common and straightforward
• with object marker: can sound more specific, more definite, or more natural in some contexts, especially with animate objects

At an early stage, it is enough to know that the version without the object marker is correct and easy to understand.

The pattern is:

• Subject + Verb + Object

So:

• Mtoto = subject
• anaogopa = verb
• mdudu huyo = object

That is the most basic and common Swahili word order, and it matches English pretty closely here:

• The child
  • is afraid of
    • that bug

Not exactly, but it often overlaps with English present meanings.

In many cases, -na- can express:

• present
• ongoing action
• a current state

With a verb like kuogopa (to fear / be afraid of), the most natural translation is often a simple present meaning:

• Mtoto anaogopa mdudu huyo = The child is afraid of that bug

So you do not need to force an English progressive like is fearing, which sounds unnatural in English.

If you want to make both child and bug plural, you would change the noun class agreement:

• Watoto wanaogopa wadudu hao.

Breakdown:

• watoto = children
• wanaogopa = they are afraid of
• wadudu = bugs/insects
• hao = those

So the original sentence is a good example of how singular noun class forms change in the plural.
