Root Explanation

Vulcanize → It is derived from 'Vulcan' (the Roman god of fire and metalworking) and the suffix '-ize' (meaning to make or to cause to become). The term 'vulcanize' refers to the process of treating rubber with heat and sulfur to improve its strength and elasticity, akin to the transformative power of fire associated with the god Vulcan.

Memory Tip

Imagine the god of fire, Vulcan, transforming rubber into something stronger and more elastic — that's how vulcanize means to make rubber better.
