Hukuman itu terlalu berat.

• hukuman = punishment / sentence / penalty
• itu = that / the
• terlalu = too / excessively
• berat = heavy, but here it means severe or harsh

So the sentence literally looks like That punishment too heavy, but natural English is That punishment is too severe / too harsh.

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

• hukuman itu = that punishment
• rumah itu = that house
• buku ini = this book

This is different from English, where this and that usually come before the noun.

Also, hukuman itu can sometimes mean not only that punishment but also the punishment, depending on context.

Indonesian often leaves out the verb to be in simple statements.

So:

• Hukuman itu terlalu berat
  literally: That punishment too severe

This is completely normal Indonesian. You do not need a word meaning is here.

In more formal or emphatic contexts, Indonesian can use words like adalah, but not in this sentence.

• natural: Hukuman itu terlalu berat.
• unnatural here: Hukuman itu adalah terlalu berat.

So just remember: in basic descriptive sentences, Indonesian often has no equivalent of is/am/are.

This is an important difference:

• terlalu berat = too severe / excessively severe
  
  • suggests a negative judgment: it goes beyond what is appropriate
• sangat berat = very severe
  
  • only describes degree, without necessarily saying it is excessive

So:

• Hukuman itu terlalu berat. = The punishment is too harsh.
• Hukuman itu sangat berat. = The punishment is very harsh.

English learners often confuse too and very, so this is a useful sentence to remember.

Yes. Berat literally means heavy, but like in English, it can also be used more figuratively.

Examples:

• tas berat = a heavy bag
• beban berat = a heavy burden
• hukuman berat = a severe punishment
• masalah berat = a serious/heavy problem

So in this sentence, berat does not mean physically heavy. It means harsh, serious, or severe.

Yes. In many contexts, noun + itu can refer to something already known in the conversation, so it may sound like the in English.

So hukuman itu could mean:

• that punishment
• the punishment

Which one is best depends on context.

For example:

• if you are pointing out a specific punishment: that punishment
• if you are talking about a punishment already mentioned: the punishment

This is one reason why itu does not always map perfectly to English that.

Yes, but the meaning changes slightly.

• Hukuman itu terlalu berat. = The punishment is too severe.
• Hukuman itu berat sekali. = The punishment is very / extremely severe.

sekali is often used to strengthen an adjective:

• besar sekali = very big
• mahal sekali = very expensive
• berat sekali = very heavy / very severe

So berat sekali is about intensity, while terlalu berat suggests excessiveness.

Yes, it is completely natural.

Hukuman itu terlalu berat sounds like normal standard Indonesian. It could appear in:

• everyday conversation
• news or legal discussion
• essays or opinion writing

It is a straightforward and idiomatic sentence.

The basic word order here is the normal one:

• Hukuman itu = subject
• terlalu berat = predicate

So:

• Hukuman itu terlalu berat. = correct

If you move the words around too much, it may sound unnatural or wrong.

For example:

• Itu hukuman terlalu berat = generally not the normal way to say it
• Terlalu berat hukuman itu = possible in special emphatic style, but not the usual neutral sentence

For learners, the safest pattern is:

noun + itu + adverb + adjective

So:

• Hukuman itu terlalu berat
• Beban itu terlalu berat
• Harga itu terlalu mahal

A simple approximate pronunciation is:

hoo-KOO-man EE-too ter-LA-loo beh-RAT

A few notes:

• u is like oo in food
• e in berat is usually a neutral uh-like sound at the start: buh-rat
• r is usually tapped or lightly rolled
• stress in Indonesian is generally not as strong or important as in English

Word by word:

• hukuman → hoo-KOO-man
• itu → EE-too
• terlalu → ter-LA-loo
• berat → buh-RAT

Yes, if you mean this punishment instead of that punishment.

• Hukuman ini terlalu berat. = This punishment is too severe.
• Hukuman itu terlalu berat. = That punishment is too severe.

So the difference is the same basic contrast as English this vs that. But remember that both ini and itu usually come after the noun in Indonesian.
