Sinister: IYKYK
The word "sinister" originates from the Latin term *sinister*, meaning "left" or "on the left side." In ancient Roman culture, the left side was often linked to bad omens and misfortune, leading to its negative connotations. Interestingly, this perception has left a lasting mark on cultural attitudes toward left-handedness. While left-handers today are celebrated for their unique perspectives and skills, the term *sinister* serves as a reminder of how historically, being left-handed was associated with malevolence and misfortune. Over time, *sinister* evolved to describe something evil or threatening, encapsulating a broader cultural shift that intertwined leftness with darker qualities.
