Bidang itu sangat luas.

In Malay, demonstratives like ini and itu usually come after the noun.

• bidang itu = that field / that area / that domain
• buku ini = this book

So even though English says that field, Malay naturally says field that.

Malay often leaves out the verb to be when linking a subject to an adjective or noun.

So:

• Bidang itu sangat luas. = That field is very broad.
• literally: field that very broad

This is completely normal in Malay. You do not need a separate word for is here.

Bidang can mean several related things depending on context, such as:

• field
• area
• domain
• subject area
• line of work

So bidang itu could refer to a literal field in some contexts, but very often it refers to an abstract area, such as a field of study, industry, or expertise.

Luas means wide, broad, spacious, or extensive.

It can be used:

• literally: for physical size or space
• figuratively: for something broad in scope, like knowledge or a field of study

So in Bidang itu sangat luas, luas may describe either physical size or a broad scope, depending on the context.

Sangat is an intensifier. It means very.

So:

• luas = broad / wide
• sangat luas = very broad / very wide

In standard Malay, sangat usually comes before the adjective it modifies.

Yes. The sentence follows a very common Malay pattern:

• Subject: Bidang itu
• Adverb of degree: sangat
• Adjective: luas

So the structure is:

[noun phrase] + [intensifier] + [adjective]

This is a normal way to make descriptive sentences in Malay.

Yes, depending on context.

Although itu often means that, it can also help mark something as specific or already known in the conversation. So bidang itu may sometimes feel like:

• that field
• the field in question
• that particular area

Malay does not have a direct word for the, so words like itu sometimes help give that definite feeling.

Yes. That is very common.

For example, luas can describe:

• physical space: Rumah itu luas. = That house is spacious.
• knowledge or experience: pengetahuan yang luas = broad knowledge
• scope or range: bidang yang luas = a broad field

So in this sentence, luas can easily describe how broad or extensive a field is in a non-physical sense.

Yes. That would simply mean:

• Bidang itu luas. = That field is broad / wide.

Adding sangat makes the statement stronger:

• Bidang itu sangat luas. = That field is very broad.

So sangat is optional if you do not want the extra emphasis.

A rough pronunciation guide is:

• Bidang ≈ bee-dahng
• itu ≈ ee-too
• sangat ≈ sah-ngat
• luas ≈ loo-as

A smoother full reading would be something like:

bee-dahng ee-too sah-ngat loo-as

The final -ng in bidang is like the sound in English sing.
