hajm

Hajm is a noun used in several languages to denote volume, size, or extent. It is derived from the Arabic حَجم (ḥajm) and is found in Arabic as well as in Persian, Urdu, Azerbaijani, Uzbek, and Turkish-influenced varieties. In general usage, hajm refers to the amount of space that a three-dimensional object occupies, or to the capacity of a container.

In Arabic, the term appears in scientific and everyday contexts, including phrases that describe the volume of liquids or the bulk of a mass. In Persian and Urdu, hajm is common in mathematics and physics as well as in ordinary language to indicate size or capacity of objects or vessels.

In Turkish and some Turkic languages, the standard word for volume is hacim; hajm is encountered mainly in older texts or in transliterations and dialectal spellings. The distinction between hacim and hajm illustrates how Arabic roots permeate neighboring languages with slight orthographic variation.

In mathematics and physics, hajm denotes the three-dimensional measure of an object, measured in cubic units such as cubic meters (m^3) or liters for practical applications. The concept underpins fields ranging from engineering to cartography and anatomy, where volume reflects the amount of space occupied by substances or bodies.
