Tanya tentang pengembirian.

Yes. It is an imperative sentence, so it means Ask about castration.

In Malay, commands are often made with just the bare verb, so there is no need to add a subject like you.

Because Malay usually leaves out the subject in commands.

So:

• Tanya tentang pengembirian. = Ask about castration.
• The you is understood automatically.

If you added awak or another pronoun, it would usually sound more marked, more emphatic, or less natural in a simple instruction.

Tanya is the base word meaning ask or question, and it is very natural in a short command.

For imperatives, Malay often uses the bare verb:

• Tanya... = Ask...
• Dengar... = Listen...
• Tunggu... = Wait...

Bertanya is also related to asking, but it is more like the full verb form used in ordinary statements or more formal language, for example:

• Dia bertanya tentang pengembirian. = He/She asked about castration.

So in this sentence, tanya is normal because it is a direct instruction.

Tentang means about, regarding, or concerning.

It introduces the topic of the question. So:

• Tanya tentang pengembirian. = Ask about castration.

Without tentang, the meaning would be less clear. Tanya often needs either:

• a person: Tanya doktor. = Ask the doctor.
• or a topic/question introduced clearly: Tanya tentang pengembirian.

Yes. A common alternative is mengenai, which also means about/regarding.

For example:

• Tanya tentang pengembirian.
• Tanya mengenai pengembirian.

Both are understandable. In many contexts, mengenai can sound a little more formal than tentang.

Pengembirian is a noun. It refers to the act, process, or result of castration.

It is formed from the root kembiri, with the noun-forming pattern peN-...-an:

• kembiri = to castrate / castration-related base
• pengembirian = castration

This pattern is very common in Malay for making abstract nouns or process nouns.

This happens because of a common sound change in Malay word formation.

When the prefix peN- is added to a root beginning with k, the k usually drops, and the prefix appears as peng-.

So:

• peN- + kembiri + -an
• becomes pengembirian

This is a normal spelling and pronunciation pattern in Malay morphology.

It sounds direct and fairly neutral, but not especially formal.

Using tanya makes it feel like a straightforward everyday instruction. If you wanted to sound more polite or formal, you could say:

• Sila tanya tentang pengembirian. = Please ask about castration.
• Tolong tanya tentang pengembirian. = Please ask about castration.

So the original sentence is natural, but quite direct.

You can add a polite word such as sila or tolong.

For example:

• Sila tanya tentang pengembirian.
• Tolong tanya tentang pengembirian.

Both soften the command. Sila is often used in polite instructions, while tolong is common in everyday polite requests.
