You’ve probably heard the term gauge, but thought it was spelled gage. However, gage is an entirely separate (and somewhat obscure) word that, while rare, can still be found from time to time. Discover the differences between these two words and which spelling to use.
Although gauge and gage are two separate words, they are often used interchangeably to refer to the more common meaning of “a measurement or instrument.” However, gauge is by far the preferred spelling for this meaning. The confusion between gauge and gage typically stems from the fact that their pronunciations are the same.
gage - a pledge or token of good faith; something that offers security
gauge - a measurement, determination or estimate
While the word gage may be obsolete, you might still encounter it in older writings. It typically refers to a token, but can also mean something for security or insurance. In Shakespearean times, it could also mean a challenge. Additionally, the gage spelling is sometimes used to mean gauge, though in this context gauge is widely agreed to be the correct spelling.
