Etymology: "Role" comes from French "rôle," which meant a roll of parchment. Actors' parts were once written out on rolled sheets, so the sense of a character's part on stage grew out of the physical scroll. The suffix "-ful," from Old English "-full," means "full of" or "characterized by," so a roleful person is one full of roles. Because it is a transparent formation, it has no single documented origin story, and it is used mostly in the sense of taking on many functions or parts in a group or activity.
