Saya makan sereal dengan susu sebelum pergi ke kantor.

Indonesian usually does not use articles like the or a/an. So sereal, susu, and kantor can often be understood from context without extra words.

It also often leaves out possessive words like my if they are obvious. So ke kantor can naturally mean to the office or to my office/work, depending on context.

Dengan usually means with. In this sentence, sereal dengan susu means cereal with milk.

A learner may notice that dengan can also mean by means of or using, depending on the sentence. Here, the meaning is simply that the cereal is accompanied by milk, not that milk is being used as a tool.

A little, yes. Grammatically, dengan susu could be read as with milk attached to sereal or to makan. But in normal context, people will understand it as eating cereal with milk.

If someone wanted to be extra clear, they might still say it exactly this way, because it is already very natural.

Because ke marks movement to a place.

• ke kantor = to the office
• di kantor = at/in the office

Since the sentence is about going somewhere, ke is the correct preposition.

In Indonesian, the subject is often omitted in a second clause if it is already clear from context.

So:

• Saya makan sereal dengan susu sebelum pergi ke kantor.

naturally means:

• I eat cereal with milk before going to the office.

The understood subject of pergi is the same as saya. You could say sebelum saya pergi ke kantor, but it is less concise and often unnecessary.

Both are possible, but makan is more common and natural in everyday speech for eat.

• makan = basic, common verb
• memakan = more formal, more explicitly transitive, sometimes used in writing or in certain contexts

For a simple sentence about breakfast, makan sounds more natural.

Indonesian verbs do not change form for tense the way English verbs do.

So makan can mean:

• eat
• am eating
• ate
• will eat

The time is usually understood from context or added words such as:

• kemarin = yesterday
• sekarang = now
• besok = tomorrow

In this sentence, without extra context, it can be read as a general habit or a present-time statement.

The given order is natural, but Indonesian word order is somewhat flexible.

For example, this is also very natural:

• Sebelum pergi ke kantor, saya makan sereal dengan susu.

This version emphasizes the time phrase first: Before going to the office, I eat cereal with milk.

Both are correct.

Saya is the more neutral and polite word for I. It works well in most situations.

Aku is also common, but it is more informal and personal. You would use it more with friends, family, or in casual speech.

So:

• saya = neutral/polite
• aku = informal

Usually kantor means office or workplace, especially an office-type place where people work.

In context, pergi ke kantor often means go to work or go to the office. It does not always focus on the physical building only; it can also imply the workplace in general.

Yes. Sereal is a standard Indonesian word, borrowed from the same source as English cereal.

Many modern food words in Indonesian are loanwords, and sereal is perfectly natural.

Yes, this sentence is natural and understandable.

A slightly different version might also be common, depending on what you want to emphasize:

• Saya sarapan sereal dengan susu sebelum pergi ke kantor.

Here, sarapan means have breakfast or breakfast. That version makes it clearer that this is breakfast.

But your original sentence is still completely fine.
