Elastikos

Elastikos is a Greek adjective meaning elastic or flexible. In Modern Greek it is used to describe objects or materials that can be stretched or deformed and then return to their original shape, as well as to denote pliability in a broader sense. The term also functions as the linguistic root for many technical terms in science and engineering, where it is commonly rendered with the prefix elasto- in English and other languages.

Etymology and usage in terminology

Elastikos derives from the Greek word ελαστικός (elastikós), tied to the concept of elasticity. The English word elastic ultimately comes via Latin elasticus from the Greek source. The root elast- is widely used in scientific vocabulary to indicate properties related to stretchability, deformability, and recovery after distortion, and it forms the basis of a broad family of terms across disciplines.

Scientific and technical usage

In physics and engineering, elasto- appears in terms such as elasticity, elastic deformation, and elastic modulus (Young's modulus), describing how materials respond to applied forces. In materials science, elastomer refers to a polymer with viscoelastic properties, capable of substantial reversible deformation; common examples include natural rubber and silicone. In biology, elastin is a key extracellular protein that provides elasticity to connective tissues such as skin, lungs, and arteries.
