Bersihkan sampah yang berselerak.

Yes. Bersihkan is an imperative form, so the sentence is giving an instruction or command: Clean up ...

In Malay, commands often begin directly with the verb, without a subject like you.

So:

• Bersihkan sampah yang berselerak. = a direct command
• English would usually understand an unstated you: (You) clean up the scattered trash.

If you want to make it more polite, you could say:

• Tolong bersihkan sampah yang berselerak. = Please clean up the scattered trash.
• Sila bersihkan sampah yang berselerak. = Please clean up the scattered trash. / Kindly clean up...

Bersih usually means clean as an adjective.

• Bilik itu bersih. = The room is clean.

Bersihkan means clean it / clean up / make it clean. It functions as a verb here, especially in a command.

So the idea is:

• bersih = clean
• bersihkan = clean something / make something clean

A related full verb form is membersihkan:

• Dia membersihkan bilik. = He/She cleans the room.
• Bersihkan bilik! = Clean the room!

Because Malay often leaves out the subject when it is obvious, especially in commands.

In English, you usually say:

• Clean up the trash.

Even though you is not spoken, it is understood. Malay works the same way here.

So in:

• Bersihkan sampah yang berselerak.

the implied subject is you.

Yang links the noun sampah to the description that follows it.

Here, it works a lot like:

• that
• which
• or sometimes that is

So:

• sampah yang berselerak = trash that is scattered around

It helps turn berselerak into a description of sampah.

A useful way to think of it is:

• noun + yang
  • description

Examples:

• orang yang tinggi = the person who is tall
• buku yang saya beli = the book that I bought
• sampah yang berselerak = the trash that is scattered around

Berselerak means scattered around, strewn about, or lying all over the place in a messy way.

It describes something not being neatly gathered.

So sampah yang berselerak gives the idea of:

• trash scattered on the floor
• litter spread around
• rubbish lying here and there

It is more vivid than just saying dirty trash. It specifically suggests a messy, spread-out situation.

Because yang makes the relationship clearer and more natural here.

In Malay, simple adjectives can often come directly after a noun:

• rumah besar = a big house
• baju merah = a red shirt

But berselerak behaves more like a descriptive clause or state here, so yang is the natural linker:

• sampah yang berselerak = trash that is scattered around

Without yang, it would sound less natural in this sentence.

Malay does not use articles like English a, an, and the in the same way.

So:

• sampah can mean trash, the trash, or even some trash, depending on context.

The listener understands the intended meaning from the situation.

That is very normal in Malay.

It does not need to be marked clearly as singular or plural.

Malay often leaves number unmarked unless it really matters.

So sampah here can be understood as:

• trash in general
• pieces of trash
• rubbish/litter collectively

Because sampah is often treated like a mass noun, English may translate it as trash, rubbish, or litter rather than trying to force a singular/plural distinction.

A normal statement would usually use membersihkan rather than bersihkan.

For example:

• Dia membersihkan sampah yang berselerak. = He/She is cleaning the scattered trash.
• Saya membersihkan sampah yang berselerak. = I am cleaning the scattered trash.

So:

• bersihkan = command form
• membersihkan = regular active verb form in statements

By itself, Bersihkan sampah yang berselerak. sounds like a direct instruction.

It is not automatically rude, but it can sound firm, depending on tone and situation. For example, it is natural from:

• a parent to a child
• a teacher to a student
• a supervisor giving instructions

If you want to soften it, add a politeness word:

• Tolong bersihkan sampah yang berselerak. = Please clean up the scattered trash.
• Sila bersihkan sampah yang berselerak. = Please / Kindly clean up the scattered trash.

The order is:

• Bersihkan = verb
• sampah = object
• yang berselerak = description of the object

So the structure is:

• Verb + object + relative description

Because it is a command, the verb comes first.

If it were a statement, you would usually add a subject at the front:

• Dia membersihkan sampah yang berselerak.

That gives:

• Subject + verb + object

A simple learner-friendly pronunciation guide would be:

• Bersihkan ≈ ber-SEEH-kahn
• sampah ≈ SAHM-pah
• yang ≈ yahng
• berselerak ≈ ber-seh-LUH-rak

A few helpful notes:

• r in Malay is usually trilled or tapped lightly.
• ng in yang is like the ng in sing.
• Malay spelling is fairly regular, so pronunciation is often easier than English spelling.

Yes, depending on context, that is a very natural English interpretation.

Bersihkan can mean more than just clean in the narrow sense. In context, it often means:

• clean up
• clear away
• tidy up

So if trash is scattered around, the practical meaning is often:

• Clean up the trash
• Clear away the scattered trash
• Pick up the trash lying around

All of those can fit the Malay sentence well.
