Questions & Answers about Saya mengantuk di perpustakaan malam ini.

Is mengantuk a verb or an adjective? In English we say “I am sleepy,” so I expect an adjective.

In Indonesian, mengantuk behaves like a stative verb: it means “to feel sleepy” or “be sleepy” in one word.

• Saya mengantuk literally = “I sleepy/feel sleepy.”
• Indonesian usually does not use a separate verb “to be” (like am/is/are) before adjectives or stative verbs.

You can think of it either as:

• verb: “I am feeling sleepy,” or
• adjective-like: “I am sleepy” but in Indonesian grammar it’s generally treated as a verb derived from kantuk (sleepiness).

Why isn’t there a word for “am” in Saya mengantuk di perpustakaan malam ini?

Indonesian normally doesn’t use a copula (a “to be” verb) the way English does.

• English: I am sleepy at the library tonight.
• Indonesian: Saya mengantuk di perpustakaan malam ini.

You simply put the subject (Saya) and then the verb or adjective (mengantuk) directly. The “am” is understood from the structure, not spoken or written.

You would only use adalah (a kind of “to be”) in specific structures, usually with nouns, not with states like mengantuk:

• Dia adalah dokter. = He/She is a doctor. But:
• Dia mengantuk. (never Dia adalah mengantuk)
