Root Explanation

Optional → It is formed from "optare" (meaning to choose) and the suffix "-al" (meaning relating to). The word "optional" refers to something that is related to a choice, indicating that it is not mandatory but rather left to one's discretion.

Memory Tip

Think of 'choosing' ('optare') something that is 'related to' ('-al') your preferences — that's why optional means it's a choice you can make.
