Emmett, a surname-turned-given-name, is a diminutive of the Germanic name Emma, which comes from the Germanic element irmin, meaning "whole" or "great." It was a popular boy's name in the early 1900s, but started losing relevance by the 1950s. Emmett returned to the top-200 in 2012 and came close to cracking the top-100 in 2021, when it was the 103rd most popular boy's name in the United States. It can be a civil rights-inspired name in honor of Emmett Till, a sporty boy's name thanks to Hall of Fame running back Emmett Smith and even a science-inspired name thanks to Emmett Brown, also known as "Doc Brown" in the "Back to Future" franchise.
