lungire

Lungire is a Romanian noun that denotes the act or result of making something longer. It corresponds to the English elongation or extension and is used to describe increasing length along a dimension, or the act of stretching.

In physics, lungire describes the change in length of a body when a force is applied. If a rod of initial length L0 is stretched, its length increases by ΔL, which is called the lungire of the rod. In materials science this concept relates to elastic deformation and Hooke's law. In biology and medicine, lungire can refer to the elongation of tissues or limbs during growth and development; it is also used in rehabilitation to describe stretching exercises, referred to as exerciții de lungire.

In everyday language, lungire can indicate extension of an object or of a time frame, though for deadlines the more common term is prelungire. The related word lungime names length as a measurement, while lungire names the process of becoming longer. The root is the adjective lung meaning long; the noun is formed with the suffix -ire.
