Word Origin & History

pencil
late 14c., "an artist's fine brush of camel hair," from O.Fr. pincel "artist's paintbrush" (Fr. pinceau), from L. penicillus "paintbrush, pencil," lit. "little tail," dim. of peniculus "brush," itself a dim. of penis "tail" (see penis). Small brushes formerly used for writing
before modern lead or chalk pencils; meaning "graphite writing implement" apparently evolved late 16c. Derogatory slang pencil-pusher "office worker" is from 1881; pencil neck "weak person" first recorded 1973. To pencil (something) in "arrange tentatively" is attested from 1942.
