elastikó

Elastikí is the feminine form of the Greek adjective ελαστική (elastikí), meaning elastic or flexible. It describes materials or objects that can be deformed under stress and return to their original shape when the stress is removed. The masculine form is ελαστικός (elastikós) and the neuter ελαστικό (elastikó). The corresponding noun for the property of being elastic is ελαστικότητα (elastikótita).

Etymology and related terms: The term derives from the Greek root élastos, meaning flexible, which has contributed to the English word elastic through historical linguistic paths. The broader semantic field includes ελαστικότητα (elasticity) as a noun and related forms used in Greek to discuss the concept in science and everyday language.

Usage in science and engineering: In Greek-language science texts, elastikí and its derivatives describe elastic behavior. Elasticity refers to a material’s ability to deform under stress and then recover its shape. Key concepts include Hooke’s law for linear elastic behavior and the modulus (such as Young’s modulus) that quantifies stiffness, typically expressed in units of pressure such as pascals.

Everyday language: Elastikí and its related forms appear in everyday Greek to describe stretchable or resilient materials. For precise use, speakers distinguish between ελαστικός, ελαστική, and ελαστικό, and use ελαστικότητα to denote elasticity as a general property.
