False Etymology - Association With Urban Legends

Association With Urban Legends

Some etymologies are part of urban legends, and seem to respond to a general taste for the surprising, counterintuitive and even scandalous. One common example has to do with the phrase rule of thumb, meaning a rough measurement. An urban legend has it that the phrase refers to an old English law under which a man could legally beat his wife with a stick no thicker than his thumb (though no such law ever existed).

In the United States, many of these scandalous legends have had to do with racism and slavery. Common words such as picnic, buck, and crowbar have been alleged to stem from derogatory terms or racist practices. The "discovery" of these alleged etymologies is often believed by those who circulate them to draw attention to racist attitudes embedded in ordinary discourse. On one occasion, the use of the word niggardly led to the resignation of a U.S. public official because it sounded similar to the word nigger, despite the two words being unrelated etymologically.
