laju

Laju is a word in Indonesian and Malay meaning speed, pace, or rate. It describes how fast something moves or how quickly a process occurs, and can apply to physical motion as well as abstract change.

In technical language, laju forms several common compounds. Laju gerak refers to speed or velocity, laju reaksi to reaction rate, laju aliran to flow rate, and laju pertumbuhan to growth rate. In economics, laju inflasi is the inflation rate, and laju pertumbuhan ekonomi denotes economic growth rate. In everyday use, people may talk about maintaining an appropriate laju kendaraan (vehicle speed) or increasing laju produksi, depending on the context.

The term is typically used as a noun and is widely understood across Indonesia and Malaysia. Kecepatan is a related term often used synonymously in everyday language, but laju emphasizes rate or tempo rather than mere absolute speed. Laju is not commonly used as a proper noun.

In summary, laju functions as a general linguistic tool to express how fast or how quickly something occurs, spanning everyday speech and a range of technical disciplines.
