Root Explanation

Copyleft is formed from "co-" (meaning together) and "left" (from the verb "to leave"). The term refers to a licensing method that allows derivative works to be made freely available, emphasizing the idea of sharing and leaving rights for others to use.

Memory Tip

Think of 'together' ('co-') and the idea of 'leaving' rights for others to use — that's why copyleft means allowing others to share and build upon your work.
