Etymology

The word "bogey" originated in the late 19th century, likely derived from the term "bogeyman," a mythical creature used to frighten children. The golf sense emerged as a playful metaphor for an imaginary opponent ("Colonel Bogey") who played at par. Later, it expanded to military slang for unidentified aircraft, retaining its association with something elusive or threatening. The morpheme "bog" preserves the original spelling tied to fear, while "-ey" functions as a noun-forming suffix.
