Although we seldom think about it, our language is in gradual but constant flux. New words come into use, old words take on new meanings and other words simply drop out of use.
If we could take a time machine back to say, 15th-century England, we’d find ourselves among English-speaking people, but we’d have a hard time both understanding them and making ourselves understood. For example, who among us knows what these words mean: forsooth, withal, bilbo, astonied, zounds, wert? They were all part of the vocabulary back then.
Even if we went back only to 1860 and stayed right here in the United States, we’d have to learn the meaning of such words as coiner, rantipole, cag-mag, whitlow and bobbish.1
Here’s a word, however, that we’d probably understand if we dropped back to either of those times: discover.
