A fisherman named Simon was given a startlingly solid nickname: Petros, Greek for “rock.” In Matthew 16:18, Jesus says, “You are Peter,” using the image of a foundation stone for the future Christian church. The name traveled from Greek Petros into Latin Petrus and then through Old English, eventually becoming one of medieval England’s most familiar names; its French relatives include Pierre and the older Anglo-French Piers, which helped produce surnames such as Pierce and Pearson. Wait, really? The apparently earthy family also includes petrous, “rocklike,” and petrify, as though Peter’s whole linguistic clan were quietly carrying a quarry around. By 1902, English speakers were also using peter as slang for the penis, probably because the name’s opening sound resembled other male-name euphemisms such as dick and willy—so one ancient “rock” ended up with a decidedly anatomical afterlife.
