careless

the word 'careless' is a transparent compound formed within english from its germanic roots. the old english noun 'caru' conveyed a sense of mental burden, such as anxiety or serious attention. when combined with the suffix '-lēas', meaning "devoid of," it created a literal meaning of "free from care or anxiety." over time, as the sense of 'care' evolved to emphasize attention and concern, the meaning of 'careless' shifted from its original neutral or positive connotation of being "untroubled" to its modern negative sense of "failing to pay proper attention" or "showing a lack of consideration," highlighting an absence of due diligence or regard.
