Adik laki-laki saya tidak suka mayones, jadi dia memilih nugget dan jagung rebus.

In Indonesian:

• adik = younger sibling
• laki-laki = male
• saya = my / I

So adik laki-laki saya literally means younger male sibling of mine, which is the natural way to say my younger brother.

A useful comparison:

• adik perempuan saya = my younger sister
• kakak laki-laki saya = my older brother
• kakak perempuan saya = my older sister

Indonesian often specifies both relative age and gender like this.

Yes, you often can.

Adik saya means my younger sibling, and in many situations the gender is either obvious from context or not important. If you want to make it clear that the sibling is male, you add laki-laki:

• adik saya = my younger sibling
• adik laki-laki saya = my younger brother

So in this sentence, laki-laki is there for clarity.

Because possession in Indonesian usually works like this:

noun + possessor

So:

• adik saya = my younger sibling
• rumah saya = my house
• buku saya = my book

This is different from English, where possession often comes first: my book. In Indonesian, the more literal order is book my.

In this sentence:

• adik laki-laki saya = younger brother my

That is the normal Indonesian structure.

Because tidak is used to negate verbs and adjectives, while bukan is mainly used to negate nouns and noun phrases.

Here, suka means to like, which functions as a verb, so you say:

• tidak suka = does not like

Compare:

• Saya tidak suka kopi. = I do not like coffee.
• Dia bukan guru. = He/She is not a teacher.

So bukan suka would sound wrong here.

In beginner learning, it is best to think of suka here as meaning to like.

For example:

• Saya suka nasi goreng. = I like fried rice.
• Dia suka musik. = He/She likes music.

In actual Indonesian grammar, suka can behave a bit differently from a typical English verb, but for practical use, treating suka as like works very well.

So tidak suka mayones simply means does not like mayonnaise.

Dia can mean either he or she. Indonesian third-person singular pronouns usually do not show gender.

So:

• dia = he / she
• ia = he / she (more formal, especially in writing)

In this sentence, we know dia refers to the younger brother because of the earlier phrase adik laki-laki saya, not because dia itself means he.

Here jadi means so, therefore, or as a result.

It links the two ideas:

• he does not like mayonnaise
• as a result, he chooses nuggets and boiled corn

So jadi is functioning as a connector between cause and result.

Very common uses:

• Saya capek, jadi saya tidur. = I’m tired, so I sleep / so I’m going to sleep.
• Hujan, jadi kami tinggal di rumah. = It’s raining, so we stay home.

Memilih means to choose. It emphasizes selection between options.

So in this sentence, the idea is that because he does not like mayonnaise, he chose:

• nugget
• jagung rebus

That may sound slightly more deliberate than simply took or ordered.

A quick note:

• base form: pilih = choose
• memilih = to choose

The prefix me- often appears on verbs in Indonesian.

Indonesian nouns usually do not change form for singular vs. plural.

So:

• nugget can mean a nugget or nuggets
• the exact number depends on context

Plurality can be shown in other ways, such as:

• context
• numbers: dua nugget = two nuggets
• reduplication: nugget-nugget = nuggets

In your sentence, nugget is understood naturally as food he chose, and Indonesian does not require an -s ending.

Because descriptive words usually come after the noun in Indonesian.

So:

• jagung rebus = boiled corn
• air panas = hot water
• nasi goreng = fried rice
• buku baru = new book

The noun comes first, then the word describing it.

So:

• jagung = corn
• rebus = boiled / boiled by cooking in water

Together, jagung rebus means boiled corn.

Yes. Dan is the standard word for and.

In the sentence:

• nugget dan jagung rebus = nuggets and boiled corn

It simply joins the two food items.

Because Indonesian does not usually use articles like a, an, or the the way English does.

So Indonesian often says things more directly:

• Dia memilih nugget. = He/She chose a nugget / the nugget / nuggets.
• Saya membeli buku. = I bought a book / the book.

The exact meaning depends on context.

This is one of the biggest differences from English: Indonesian nouns usually appear without articles.

The sentence is built in a very straightforward way:

• Adik laki-laki saya = subject
• tidak suka mayones = first statement about him
• jadi = connector (so)
• dia memilih nugget dan jagung rebus = result clause

So the rough structure is:

[Subject] + [negative verb phrase] + [object], jadi [pronoun] + [verb] + [objects]

This kind of sentence pattern is very common and natural in Indonesian.
