pencil (n.)

"the male organ of copulation," 1670s, from French pénis or directly from Latin pēnis "penis," earlier "tail," from PIE *pes-, usually said to be originally "penis" (source also of Sanskrit pasas-, Greek peos, posthe "penis," probably also Old English fæsl "progeny, offspring," Old Norse fösull, German Fasel "young of animals, brood"). But de Vaan writes that "the meaning of pēnītus ['furnished with a tail'] as well as general semantic considerations suggest that the meaning 'tail' is original, and 'penis' metaphorically derived from it." The proper plural is penes. The adjective is penial. In psychological writing, the term penis envy is attested by 1922.

jocular or slighting term for a clerk or author, by 1820, from pen (n.1) + driver. Earlier was quill-driver (by 1760).

The Author goes on, and tells us, "that the two thousand hogs were not driven into the sea by evil spirits, but by the two madmen, who, in one of their frantic fits, frightened them into it."— But is it not more than intimated that the men were restored to their right mind before the hogs took to their heels? Besides, that two madmen should drive two thousand such ungovernable creatures as hogs one way, does, I think, exceed the belief of any hog-driver on the road, if not of the pen-driver in his closet.
