Where did the word swagger originate?

The Word "swagger" is believed to have originated in the early 16th century, derived from the verb "swag," which means to sway or rock. It was initially used to describe a style of walking that exudes confidence or arrogance. The term was popularized in literature, notably in Shakespeare's works, where it often conveyed a sense of bravado or ostentation. Over time, "swagger" has evolved to encompass not just physical demeanor but also a broader attitude of self-assuredness.
