rusak

Rusak is an adjective in Indonesian and Malay meaning damaged, broken, or spoiled. It is used to describe objects, mechanisms, or conditions that are not functioning normally, as well as things that have deteriorated or failed in some way. The term is common in everyday speech and in written language.

In usage, rusak often appears with physical items such as devices, structures, or materials: for example, "Kamera itu rusak" (That camera is damaged), "Baterai ini rusak" (This battery is faulty), or "Buku itu rusak karena basah" (That book is damaged from getting wet). It can also describe non-physical states, such as a malfunctioning program, a corrupted file, or a plan that has gone wrong: "File itu rusak," "Rencana itu rusak jika tidak ada persiapan." The antonym or opposite sense is berfungsi, baik, or normal.

Forms and related words. The related verb merusak means to damage or to corrupt, and the noun kerusakan denotes damage or destruction. In many contexts, rusak serves as a stative descriptor (a state of being damaged) rather than a dynamic action. Adverbs and intensifiers may modify rusak to express degree, for example rusak parah meaning severely damaged.

Etymology and scope. Rusak is rooted in Malay and Indonesian and has cognates across related Austronesian languages. While predominantly technical in everyday use, the term can also appear in figurative speech to indicate poor quality, corruption, or deterioration of conditions.
