Etymology : Circumscribe has a lot of relatives in English. Its Latin predecessor circumscribere (which roughly translates as “to draw a circle around”) derives from circum-, meaning “circle,” and scribere, meaning “to write or draw.” Among the many descendants of circum- are circuit, circumference, circumnavigate, circumspect, circumstance, and circumvent. Scribere gave us such words as scribe and scribble, as well as ascribe, describe, and transcribe, among others. Circumscribe was first recorded in the 15th century; it was originally spelled circumscrive, but by the end of the century the circumscribe spelling had also appeared.
