Is Phi Mu a fraternity or sorority?

The Society joined the National Panhellenic Conference in 1904, taking on the Greek letters Phi Mu. Phi Mu is referred to as a women’s fraternity since some sororities predate the term “sorority” and are thus known as “fraternities for women.” Phi Mu is one such sorority, and its formal name is Phi Mu Fraternity.
