aktif

Aktif is an adjective meaning "active" or "in operation" in several languages, including Indonesian, Malay, Turkish, and Dutch-influenced varieties. The form derives from the Latin activus, passing through French actif and Dutch actief, among other routes, and has been incorporated into many vocabularies to denote energy, participation, or functional status.

In Indonesian usage, akti f describes people, processes, and objects that are functioning or engaged. Common phrases include gaya hidup aktif (active lifestyle), masa aktif (active period), and keaktifan (activeness). The verb mengaktifkan means to activate, and the noun aktivitas or keaktifan expresses activity or activeness. The term also appears in compound words such as perangkat aktif or komponen aktif to indicate devices or components that operate with power.

In technology and electronics, the term distinguishes active components from passive components. Aktif components require power to operate, such as transistors, operational amplifiers, and integrated circuits, while pasif components like resistors and capacitors do not supply power. The concept is also used in computing and communications to describe active sessions, active users, or other elements that are currently in operation.

In Turkish, aktif retains the same core meaning of "active" and is used across contexts such as work, sports, and daily life. Similar usage appears in Malay and Indonesian, where it forms part of common expressions describing engagement, participation, and functionality. Related terms include aktivitas (activity) and keaktifan (activeness), reflecting the root meaning across languages.

Etymologically, aktif reflects a shared Indo-European lineage linked to Latin activus and its descendants in Romance and Germanic languages. Its broad cross-linguistic presence highlights a common concept of energy, movement, and operational state.
