Kapal itu tenggelam di laut.

In Indonesian, demonstratives like ini (this) and itu (that/the) usually come after the noun.

So:

• kapal itu = that ship / the ship
• rumah ini = this house

This is one of the first word-order differences English speakers notice. In English, demonstratives go before the noun; in Indonesian, they normally go after it.

In this sentence, kapal itu can often be understood as the ship or that ship, depending on context.

It can mean either, depending on context.

Indonesian does not have a separate word that works exactly like English the. Because of that, itu is often used not only for that, but also to refer to something specific and already identifiable, which can sound like the in English.

So:

• kapal itu = that ship
• kapal itu can also feel like the ship

The exact interpretation depends on the situation and the surrounding conversation.

Indonesian verbs do not change form for tense the way English verbs do. The verb tenggelam stays the same.

So by itself, Kapal itu tenggelam di laut does not mark tense explicitly. The time is usually understood from context, or from time words such as:

• kemarin = yesterday
• sedang = in progress / currently
• sudah = already
• akan = will

For example:

• Kapal itu tenggelam kemarin. = The ship sank yesterday.
• Kapal itu sedang tenggelam. = The ship is sinking.
• Kapal itu sudah tenggelam. = The ship has already sunk.

Without extra markers, a simple translation like The ship sank in the sea or The ship sank at sea is often chosen based on context.

In this sentence, tenggelam functions as the main verb.

It means to sink or to be submerged. It is often an intransitive verb, meaning it does not take a direct object.

Examples:

• Kapal itu tenggelam. = The ship sank.
• Matahari tenggelam. = The sun sets / The sun goes down.

So in Kapal itu tenggelam di laut, tenggelam is the action/state of the subject kapal itu.

Indonesian often does not use a verb equivalent to English to be in simple sentences.

English needs forms like is, am, and are in many places. Indonesian usually does not.

So instead of saying something like The ship is sank or The ship is in the sea, Indonesian often simply places the words together without a copula.

In this sentence, tenggelam is already the main verb, so no extra is is needed:

• Kapal itu tenggelam di laut.

This is completely normal Indonesian sentence structure.

Di is a preposition here, meaning in, at, or on, depending on context.
Laut means sea.

So:

• di laut = in the sea / at sea

It is written as two separate words because di is a preposition in this sentence.

This is important because Indonesian also has a prefix di- used for passive verbs, and that one is written attached to the verb.

Compare:

• di laut = in the sea → separate, because di is a preposition
• ditulis = written → attached, because di- is a verb prefix

This spelling difference is very important in Indonesian.

Indonesian does not have articles like English a, an, and the.

So laut by itself can mean:

• sea
• the sea
• sometimes even a sea, depending on context

In di laut, English usually translates it as in the sea or at sea, but Indonesian does not need a separate word for the.

Laut most commonly means sea, but in some contexts English may translate it as ocean, especially if the distinction is not important.

Still, the most direct basic meaning is sea.

If someone specifically wants to say ocean, Indonesian often uses samudra.

So:

• laut = sea
• samudra = ocean

But in everyday usage, laut is very common and natural.

Yes. That is possible.

Indonesian word order is fairly flexible, especially when you want to emphasize location, time, or another part of the sentence.

Compare:

• Kapal itu tenggelam di laut. = neutral order
• Di laut, kapal itu tenggelam. = emphasizes the location

Both are grammatical. The first version is the more straightforward, neutral sentence.

Kapal usually refers to a relatively large vessel, so ship is often the best translation.

For smaller boats, Indonesian often uses perahu.

So a rough distinction is:

• kapal = ship, vessel
• perahu = boat

However, exact translation can still depend on context. In beginner materials, kapal is often translated simply as ship.

It is possible, but it feels less specific.

• Kapal itu tenggelam di laut. = That/The ship sank in the sea
• Kapal tenggelam di laut. = A ship sinks/sank in the sea or Ships sink in the sea, depending on context

Without itu, the noun kapal is less clearly identified. Adding itu makes it sound like a particular ship the speaker and listener both know about, or at least a specific ship being discussed.

So the version with itu is more specific and definite.

It is neither passive in form nor a transitive active sentence with an object. It is best understood as an intransitive sentence.

The subject is:

• kapal itu = the ship / that ship

The verb is:

• tenggelam = sink / sank

There is no direct object. The ship is not doing something to another thing; rather, the ship itself undergoes the event of sinking.

So this is a simple intransitive clause, which is very common in Indonesian.
