bae (35)

1. clipping; noun
   A significant other, or something that is similarly endearing and lovable
    

   The meaning of bae has been widened from that of “babe” or “baby” to a general term describing something endearing or well liked. It has also undergone zero derivation, being used as an adjective describing something that could be a bae; “That’s so bae!” and “That’s my bae!” are both valid usages of bae. One possibility for the coining of this neologism is a general trend of shorter words within slang; baby or babe have two syllables each, while bae only has one. Bae also has a folk etymology, a backronym: “Before anyone else” (Washington Post, The Lamentable Death of Bae)

   Etymology : Formed from clipping of English babe.
