Berhati-hati di garis batal dan alur.

Berhati-hati means be careful or take care.

A learner-friendly way to think about it:

• hati literally means heart
• ber- is a common prefix
• the repetition in hati-hati helps form the idea of being cautious

But in practice, it is best learned as a fixed expression: berhati-hati = to be careful.

Malay also very commonly uses the shorter form hati-hati! with the same basic meaning.

Because Malay often leaves out the subject in commands and warnings.

So:

• Berhati-hati ... = Be careful ...

The understood subject is you, but Malay does not need to say it.

This is very normal in instructions, signs, and warnings.

Here, di is a preposition meaning at, in, or on, depending on context.

In this sentence, it marks the place where the caution applies:

• di garis batal dan alur = at/on the foul line and the groove/gutter/track depending on context

A very important spelling point for learners:

• di as a preposition is written separately
• di- as a passive verb prefix is written attached

For example:

• di sini = here
• dibuka = opened

So di garis is correct, not digaris.

Because Malay usually puts the main noun first and the describing word after it.

So:

• garis = line
• batal describes that line

This is different from English, where modifiers often come before the noun.

Compare:

• English: big house
• Malay: rumah besar

So garis batal follows normal Malay word order.

Yes, batal often means cancelled, void, or invalid.

In combinations with other words, it can also carry the idea of something that does not count or causes disqualification/violation, depending on the context.

So in a technical or sports-related phrase like garis batal, batal may correspond to something like:

• invalid
• foul
• void

The exact English label depends on the setting, but the Malay logic is still tied to the idea of something not counting or being invalid.

Alur has several possible meanings depending on context. Common ones include:

• groove
• channel
• rut
• track
• furrow

So it is a fairly flexible word. In this sentence, it refers to some kind of physical channel or track-like part of the area being talked about.

This is a good example of a Malay word whose exact English translation changes with context.

Because one preposition can apply to two nouns joined by dan.

So:

• di garis batal dan alur

means:

• at the foul line and the groove/gutter/track

Malay does not need to repeat di before both nouns.

English works similarly:

• at the door and the window

not necessarily

• at the door and at the window

Repeating the preposition is possible in some cases, but it is not required here.

Dan means and.

It joins:

• garis batal
• alur

So the warning applies to both things together.

This is a very basic and common conjunction in Malay.

Because Malay normally does not use articles like English the, a, or an.

So a phrase like:

• garis batal

can mean:

• a foul line
• the foul line

depending on context.

Malay leaves that kind of information to the situation, not to an article.

This is one of the biggest differences English speakers notice early on.

Usually, yes.

Both are correct and natural, but:

• hati-hati is very common in everyday speech and casual warnings
• berhati-hati sounds a bit fuller and slightly more formal or careful in tone

So on a sign or in written instructions, berhati-hati is perfectly normal. In speech, many people would simply say Hati-hati!

Yes. In Malay, short warning-style sentences are very common and completely natural.

This sentence works as an instruction or caution notice:

• Berhati-hati di garis batal dan alur.

Malay often allows concise structures like this, especially in:

• signs
• announcements
• safety warnings
• instructions

So even though it may feel shorter than an English equivalent, it is still a complete and usable sentence.
