Commit to Learning the History of Espouse

As you might guess, the words espouse and spouse are hitched, both coming from the Latin verb spondēre, meaning “to promise” or “to betroth.” In fact, the two were once completely interchangeable, with each serving as a noun meaning “a newly married person” or “a partner in marriage” and also as a verb meaning “to marry.” Their semantic separation began when the noun espouse fell out of use. Nowadays, espouse is almost exclusively encountered as a verb used in the figuratively extended sense “to commit to and support as a cause.”
