Gauge is a word that is used to refer to measuring instruments that measure a physical characteristic of an object. Gage is a word that has two meanings, one of which is pledge. This means it is used to refer to a surety or an item that is deposited in lieu of a loan. The word has the same root as we find in engage and wage. Engage reflects one’s promise to marry or the willingness to enter an agreement. The root also finds use in mortgage.
