Are Indonesian and Malaysian Similar? Explaining the Differences and Relationship

Are Indonesian and Malaysian Similar? Explaining the Differences and Relationship

Have you ever heard that Indonesian and Malaysian are very similar languages?

In fact, many travelers to Southeast Asia often say that "the same kind of words worked in both Indonesia and Malaysia."

So, what exactly are the differences between Indonesian and Malaysian?

Indonesian and Malaysian are "Similar but Not Identical" Languages

To give you the answer first, Indonesian and Malaysian are languages that are "similar but not the same."

For example, if a speaker of standard Japanese (Kanto dialect) hears the Satsuma or Tsugaru dialects, they might roughly understand the meaning but not comprehend it completely.

Also, between the Kanto and Kansai dialects in Japan, there are differences in specific word usage for greetings or proper nouns.

The relationship between Indonesian and Malaysian is somewhat similar to that sensation.

However, the difference lies in the fact that they are recognized as the standard languages of separate countries, rather than just dialects.

To compare them to other languages, it is said that the difference is greater than that between British English and American English, yet they are closer than Spanish and Portuguese.

Many travelers experience that "studying Indonesian also worked in Malaysia."

Conversely, there are cases where "learning Malaysian allowed me to get by in Indonesia."

However, it is often the case that communication is not perfectly seamless.

  • Finding unknown words when reading a menu at a restaurant
  • Being unable to understand what a taxi driver is saying

Such occurrences are not uncommon.

When deciding whether to learn Indonesian or Malaysian, this "similar but different" distinction and relationship is an important point.

How Many People Speak Indonesian and Malaysian?

How Many People Speak Indonesian and Malaysian?

Next, we will briefly introduce how many people speak Indonesian and Malaysian.

Indonesian Has Over 200 Million Speakers!

Indonesian is a language used by over 200 million people.

The population of Indonesia is approximately 280 million, making it the 4th largest in the world.

Since Indonesian is the common language, almost all Indonesians can understand and speak it.

The most significant characteristic of Indonesian is that it is considered a crucial language for unifying the nation of Indonesia.

In Indonesia, over 700 regional languages such as Javanese, Sundanese, and Balinese coexist, but Indonesian was chosen as the common language instead of any of those.

This was done to prevent any specific language (and ethnic group) from dominating the country.

For this reason, many Indonesian citizens do not have Indonesian as their native tongue, and it is often a second language used in formal settings.

However, in recent years, the number of people who speak Indonesian as their first language has been increasing.

In this way, Indonesian is one of the most spoken languages in Southeast Asia.

Even on a global scale, Indonesian ranks within the top 10 languages by number of speakers.

Malaysian (Malay) Has Approximately 25 Million Speakers

The number of Malaysian (Malay) speakers is estimated to be around 25 million.

Malaysia has a population of approximately 34 million and is a multi-ethnic nation: Malays make up about 58%, and when combined with other indigenous groups (Bumiputera), they account for about 70%. Chinese make up about 22%, and Indians about 7%.

As the national language, Malaysian (Malay) is studied by all citizens in school.

Additionally, there are Malay speakers in Singapore and Brunei.

In Singapore specifically, Malay is one of the official languages, and the lyrics of the national anthem are written in Malay.

Furthermore, dialects of Malay are spoken in the three southern provinces of Thailand (Pattani, Yala, and Narathiwat).

Historically, it was also used as a trade language in the southern Philippines.

While there are differences between Indonesian and Malaysian, looking at the Malay-speaking world as a whole, it is an important language used across a vast region.

What are the Differences Between Indonesian and Malaysian? Differences in Expression through Vocabulary

What are the Differences Between Indonesian and Malaysian? Differences in Expression through Vocabulary

A clear example that illustrates the differences and relationship between Indonesian and Malaysian can be found in common everyday vocabulary.

Let's look at specific examples where different words are used for the same meaning.

Why are There Vocabulary Differences Between Indonesian and Malaysian?

The primary reason for the differences between Indonesian and Malaysian lies in the history of the colonial era.

In Indonesia, which was under Dutch rule, and Malaysia, which was under British rule, different loanwords were introduced respectively.

As a result, differences emerged in the words used to refer to the exact same things.

Furthermore, the fact that Indonesia and Malaysia developed Indonesian and Malaysian as unique languages after gaining independence following World War II is also related to the differences in vocabulary.

Differences Between Indonesian and Malaysian Seen in Everyday Terms

So, specifically, what kind of vocabulary differences are there?

For example, when you go shopping, you need a bag or sack to put your items in.

This bag is called:

  • "tas" in Indonesian, derived from Dutch
  • "beg" in Malaysian, derived from English

Also, the towel used after a bath is called:

  • "handuk" in Indonesian, derived from Dutch
  • "tuala" in Malaysian, derived from Portuguese

The bag example comes from the difference between Dutch and English, while the towel example comes from the difference between Dutch and Portuguese.

In addition, there are differences that emerged because Indonesian and Malaysian developed separately.

For instance, a mobile phone is called "ponsel" in Indonesian.

This is an abbreviation of "telepon seluler" (cellular telephone).

On the other hand, in Malaysian, it is called "telefon bimbit."

Bimbit is a Malay word meaning "to carry in one's hand," so it means "a phone that can be carried."

In this way, differences between Indonesian and Malaysian continue to be created even in modern times.

Can Indonesian and Malaysian Speakers Understand Each Other?

As shown, there are differences in vocabulary and expression between Indonesian and Malaysian.

However, mutual intelligibility is basically possible.

Linguistically, it is estimated that approximately 80% of the vocabulary is shared between the two languages.

Differences between Indonesian and Malaysian are particularly minimal in formal settings, such as news programs, official documents, and academic texts.

This is because both countries have a history of jointly promoting language standardization.

In the fields of business and academia, communication can often be achieved without being conscious of the differences between Indonesian and Malaysian.

Caution Required in Daily Conversation

However, in casual everyday conversation, there are often many differences between Indonesian and Malaysian.

When slang, youth speak, or regional dialects that have developed uniquely in each country are mixed in, communication can become difficult.

When watching TV shows or YouTube videos, these differences become quite apparent.

In basic business or travel scenarios, communication is possible despite the differences between Indonesian and Malaysian.

However, if you wish to build deeper relationships or discuss more specialized content, it is recommended to study the other's language thoroughly.

What are the Benefits of Choosing Malaysian?

On the other hand, there are also many benefits to choosing Malaysian (Malay).

Malaysia is a country with a stable economy within Southeast Asia.

It is very attractive to learn a language that is usable in multiple countries, including Singapore and Brunei.

Since Malaysian is strongly influenced by English, it also features a lot of vocabulary that is easy for English speakers to become familiar with.

Furthermore, because Malaysia is a multi-ethnic nation where English and Chinese are also widely understood, it is an advantage for those with experience learning English or Chinese to find it familiar.

For those considering business or long-term stays in Malaysia, studying Malaysian is a recommended choice.

Learning One Language Makes It Easy to Acquire the Other

While there are differences between Indonesian and Malaysian, they are deeply related languages with common foundations.

If you master one, it is easy to learn the other.

Since the grammatical structure is the same, you just need to learn the differences in vocabulary and pronunciation.

For example, even if you move to Malaysia after learning Indonesian, you can sufficiently master Malaysian in a few months.

If you become able to distinguish between Indonesian and Malaysian while being conscious of their differences, you will be able to communicate across a wide area of Southeast Asia.

Why are Indonesian and Malaysian Similar? Explaining the Relationship Between the Two Languages

Why are Indonesian and Malaysian Similar? Explaining the Relationship Between the Two Languages

There are historical reasons why Indonesian and Malaysian are similar.

We will further explain the relationship between the two languages from a historical perspective.

Development from the Malay of the Malacca Sultanate

The relationship between Indonesian and Malaysian is rooted in the shared history of both languages.

From the 15th to the 16th century, the Malacca Sultanate flourished in the region encompassing present-day Indonesia and Malaysia.

During this era, Malay functioned as the common language (lingua franca) for the entire region.

In Malacca, where merchants from Arabia, Persia, India, and China gathered, Malay was indispensable for trade.

With the prosperity of the Malacca Sultanate, Classical Malay became refined and developed as a language of literature and administration.

The influence of Islamic culture was also significant, and many Arabic and Persian words were incorporated into Malay.

The Malay of this era serves as the common ancestor of modern Indonesian and Malaysian.

Differences Between the Two Languages are Related to Colonial Rule

The major turning point that created the differences between Indonesian and Malaysian is related to colonial rule by various European nations.

In the 16th century, Portugal conquered Malacca, and later the Netherlands came to rule Indonesia, while Britain ruled the Malay Peninsula.

Because the Netherlands ruled Indonesia for over 300 years, the Dutch language exerted a significant influence on the language.

On the other hand, in the Malay Peninsula under British rule, the language was strongly influenced by English.

This became a major factor in creating the current differences between Indonesian and Malaysian.

Unifying Language in Indonesia as Indonesian

In 1928, young Indonesians declared the "Youth Pledge" and decided to adopt Indonesian as the unified language.

In Indonesia, various languages such as Javanese were used in different regions, but by choosing Indonesian—based on Malay—rather than any other language as the unified tongue, they ensured that no specific ethnic group would hold linguistic or political dominance.

This led to the birth of Indonesia's unique national language, while still being based on Malay.

This historical decision also became a divergence point where Indonesian and Malaysian began walking separate paths.

Relationship Between Modern Indonesian and Malaysian

Furthermore, the fact that Indonesia and Malaysia developed them as unique national languages after independence is another reason for the differences between the two.

Indonesia is flexible regarding language and maintains an attitude of actively accepting new words.

There is a tendency to rapidly incorporate loanwords from foreign languages as needed.

Meanwhile, Malaysia took a different approach.

Malaysia is also a multi-ethnic nation where Malay, Chinese, Indian, and other diverse ethnic groups coexist.

However, in language policy, Malaysia tended to try to maintain the purity of traditional Malay.

In Malaysia, instead of using loanwords as they are, there is an effort to create new words in Malay as much as possible.

The difference between Indonesian and Malaysian is also related to these different philosophies regarding language.

In this way, differences between Indonesian and Malaysian have emerged not only in the past but continue to be created today.

Learning Indonesian or Malaysian also means understanding the culture, values, and history of each country.

Whichever you choose, Indonesian or Malaysian, you will be able to touch upon the rich historical story behind it.
