A recent visit to friends with youngsters reminded us about the place of family words. A family word, according to word collector Paul Dickson, is a "linguistic curiosity in that it is only understood by a very small circle . . . more often than not, family words can be traced back to a kid or a grandparent."
Usually, family words are coined to fill a gap. There are a number of coded dinner-table messages, such as F.H.B. and M.Y.M. Those acronyms (which translate as "Family Hold Back" and "Mind Your Manners," respectively) allow family members to discreetly remind each other of what needs to be done.
Some family words are even easier to interpret. Glassable is one family's term for fragile items that children shouldn't touch, while chokable refers to items that children should be cautious about eating.
Still other family terms are onomatopoeic. Eekser refers to the lever on a metal ice cube tray; its name comes from the sound it makes when it's pulled; clunk-waa names the phenomenon of a child falling out of bed; and gummatajumma is what some folks call the car ride over railroad tracks.
But the origin behind other family terms remains less than obvious. Consider bunce, truna, tumpee, and canoost—all names for what most of us know as the heel of a loaf of bread.
