In the Middle Ages, Thome Fole was a name assigned to those perceived to be of little intelligence. This eventually evolved into the spelling tomfool, which, when capitalized, also referred to a professional clown or a buffoon in a play or pageant. The name Tom seems to have been chosen for its common-man quality, much like Joe Blow for an ordinary person or Johnny Reb for a soldier in the Confederate army, but tomfoolery need not apply strictly to actions by men. In Lucy Maud Montgomery's Anne of Green Gables (1908), for example, Marilla Cuthbert complains of Anne: "She's gadding off somewhere with Diana, writing stories or practicing dialogues or some such tomfoolery, and never thinking once about the time or her duties."
