Did You Know?
The earliest known use of "threshold" in the English language is from Alfred the Great's Old English translation of the Roman philosopher Boethius's De consolatione philosophiae. In this translation, which was written around 888, "threshold" appears as "þeorscwold" (that first letter is called a thorn and it was used in Old English and Middle English to indicate the sounds produced by "th" in "thin" and "this"). The origins of this Old English word are not known, though it is believed to be related to Old English "threscan," from which we get the words thresh, meaning "to separate seed from (a harvested plant) using a machine or tool" and "thrash," meaning, among other things "to beat soundly with or as if with a stick or whip."
