reckless (English)
Where does "reckless" come from?
The English adjective 'reckless' descends from the Middle English 'rekles'[1]. This form comes directly from the Old English 'rēcelēas', meaning reckless, careless, or negligent[1]. The Old English word is a compound built from 'rēċan', meaning to care, combined with the suffix '-lēas'[2]. The root for caring traces further back through Proto-West Germanic and Proto-Germanic 'rōkijaną'[4], ultimately connecting to a Proto-Indo-European root meaning to help[5]. Meanwhile, the suffix descends from Proto-Germanic '*lausaz' meaning loose or free[6], derived from the verb meaning to lose[8].

- The Proto-Germanic root for care is compared with Ancient Greek arēgō meaning to aid or ward off, though this connection is part of a reconstructed etymological lineage. [5]
