Richard McClintock, a Latin scholar from Hampden-Sydney College, is credited with discovering the source behind the ubiquitous filler text. In seeing a sample of lorem ipsum, his interest was piqued by consectetur—a genuine, albeit rare, Latin word. Consulting a Latin dictionary led McClintock to a passage from De Finibus Bonorum et Malorum On the Extremes of Good and Evil, a first-century B.C. text from the Roman.

Carried only by professionals

So when is it okay to use lorem ipsum? First, lorem ipsum works well for staging. It’s like the props in a furniture store—filler text makes it look like someone is home. The same Wordpress template might eventually be home to a fitness blog, a photography website, or the online journal of a cupcake fanatic. Lorem ipsum helps them imagine what the lived-in website might look like.
