reckless
UK: ˈrekləs | US: ˈrekləs
adj. acting without thinking or caring about the consequences; rash or heedless
The word "reckless" originates from Old English receleas, combining "reck" (from reccan, meaning "to care or heed") and the suffix "-less" (meaning "without"). Over time, "reck" fell out of common usage, but its meaning persists in "reckless," which literally translates to "without care." The term evolved to describe behavior characterized by a lack of caution or forethought, reflecting its original components vividly.
