Elasticized → It is formed from "elastic" (from Greek "elastikos", meaning flexible or able to return to its original shape) and "-ize" (meaning to make or to become). The word "elasticized" means to make something flexible or able to return to its original shape, often referring to materials that have been treated to have elasticity.
Think of something being made 'flexible' ('elastic') and then 'becoming' that way ('-ize'). This helps you remember that 'elasticized' means made flexible.
