terluar

Terluar is an Indonesian adjective meaning outermost or external. It is formed from the root luar, meaning outer or exterior, with the prefix ter-, which in Indonesian commonly marks a superlative or extremal degree. As a result, terluar describes something located farthest from a center or interior boundary, or lying on the periphery of a defined area.

Usage of terluar spans geographic, architectural, biological, and everyday language. Examples include wilayah terluar negara (the outermost region of a country), pulau terluar (outermost island), lapisan terluar kulit (outer layer of the skin), and permukaan terluar sebuah benda (the outer surface of an object). In most cases, terluar modifiers precede the noun they describe and function adjectivally rather than as a standalone noun.

Grammar notes: Terluar is typically used before the noun it modifies, e.g., batas terluar kota. When comparing multiple areas, other forms such as terluas (widest) exist, but terluar conveys extremity rather than a simple comparative.

See also terms that are related in meaning include luar (outer), bagian luar (outer part), terluas (the most extensive), terdekat (the nearest), and batas (boundary). In formal writing, more precise terms such as periphery, outer boundary, or frontier may be employed depending on context.
