It’s time again for Percussive Etymology (now sporting its very own header, courtesy of the wife). In this fortnightly feature my trusty hammer and I will explore the origins of one of the many quirky phrases contained in the English language.
The continued positive response to this feature truly warms my heart. Following the brass monkey shenanigans I have been inundated with suggestions of other phrases to
mutilate explain, and even a specific request to once more debunk a popular fallacy regarding the origins of a particular expression. While mythbusting was not part of my initial plan for this feature, I acknowledge that I can provide a valuable service to the linguistic sciences by making this small addition.
In that vein we will today address the expression “rule of thumb”, suggested by Misha Burnett. (By the way, Misha recently published the final instalment in his Book of Lost Doors trilogy, The Worms of Heaven. Why don’t you stop by his blog and give it a look?)
