Definition & Meaning: elast(o)- Word Root

The word elast(o)- is derived from the Greek word elastos, which means ductile or flexible. This root is evident in the word “elasticity,” a term we frequently encounter, making it easier to comprehend the meaning of words containing the root “elast(o)-“.

To better understand, let’s break down the word elastomer:

  • Elast(o)-: ductile or flexible
  • -mer: a suffix meaning “part” or “segment”

Thus, an elastomer is a natural or synthetic polymer having elastic properties, such as rubber.

Example Sentence: “Elastomers were created as an alternative to natural rubber and have expanded to include materials from thermoset rubber polymers.”
