Sometimes a word is just a word. But other times, it’s an indicator of something more troubling on the part of the speaker. Take, for example, the word “boy.” When being used to refer to a small child, most of us don’t think twice. But when the word “boy” refers to an adult black man, and the speaker is his white supervisor who’s just passed him up for a promotion, it takes on a much different meaning.

It’s for this reason that John Hithon, an employee of the Tyson chicken processing plant in Gadsden, Alabama, sued his employers for workplace discrimination.
