The quality of being unable to change or adapt easily.
The inelasticity of the material made it difficult to shape into different forms.
Inelasticity → It is formed from "in-" (meaning not) and "elasticus" (from Latin, meaning flexible or stretchable) and the suffix "-ity" (meaning the state or condition of). The word "inelasticity" refers to the state of being not flexible or not able to stretch.
Think of 'not' ('in-') being combined with 'flexible' ('elasticus') to remember that 'inelasticity' means the condition of being not flexible.
