Suffixes: kah & lah

01

The Question Suffix -kah

The suffix -kah is used to mark a sentence as a question. While intonation alone can signal a question in spoken language, -kah provides grammatical clarity, especially in writing or formal speech.

Its most common use is in the word apakah. By attaching -kah to apa (what), the word functions as a particle to introduce Yes/No questions, similar to the English "Do," "Does," or "Is."

• Apakah kamu suka kopi?

  Do you like coffee?

• Apakah ini benar?

  Is this correct?

You can also attach -kah to other question words (interrogatives) like siapa (who) or di mana (where) to make them more formal or emphatic.

• Siapakah orang itu?

  Who is that person?

• Di manakah stasiun kereta?

  Where is the train station?

Additionally, -kah can be attached to the specific word in the sentence that is being questioned, shifting the focus of the inquiry to that element.

• Benarkah dia sudah pergi?

  Is it true that he has already left?

02

The Emphasis Suffix -lah

The suffix -lah is a particle used to emphasize the word it is attached to. It directs the listener's attention to a specific part of the sentence, often asserting that "this specific thing" is the subject of discussion.

When attached to a noun or pronoun, it often carries the meaning of "precisely this" or "it is this one."

• Dialah yang mengambil buku itu.

  It was he who took the book.

• Inilah masalah utamanya.

  This is the main problem.

03

Softening Commands with -lah

Another essential function of -lah is to soften the tone of imperative sentences (commands). Using a bare verb to give a command can sound harsh or rude. Attaching -lah turns the command into a polite request, a strong suggestion, or an invitation.

• Masuklah.

  Please come in.

• Makanlah sebelum dingin.

  Please eat before it gets cold.

• Janganlah marah.

  Please do not be angry.

In these contexts, the suffix acts as a buffer, making the speaker sound more refined and respectful.
