Questions & Answers about Wi‑Fi di perpustakaan stabil pagi ini.

Do I need a verb like “is” here? Why isn’t there adalah?

Indonesian doesn’t require a copula with adjectives. Wi‑Fi di perpustakaan stabil already means “The Wi‑Fi at the library is stable.” Use adalah mainly when the predicate is a noun or for emphasis.

• Correct: Wi‑Fi di perpustakaan stabil.
• Unnatural: Wi‑Fi di perpustakaan adalah stabil.
• With a noun: Wi‑Fi di perpustakaan adalah jaringan nirkabel.

What does di mean, and how is it different from ke?

di marks location (“at/in/on”), while ke marks movement (“to/toward”).

• di perpustakaan = at the library
• ke perpustakaan = to the library

Should di be written together like diperpustakaan?

No. As a preposition meaning “at/in,” di is written separately: di perpustakaan. It’s only attached when it’s the passive prefix on a verb (e.g., ditulis “written”).

What exactly does pagi ini mean? How is it different from tadi pagi or pada pagi ini?

• pagi ini = “this morning” (today’s morning; neutral, often still relevant now).
• = “earlier this morning” (clearly past).
