wireless
UK: ˈwaɪələs | US: ˈwaɪərləs
adj. lacking or not requiring physical wires or cables
n. a system or device that operates without wired connections
The word "wireless" emerged in the late 19th century as a compound of "wire" (from Old English wīr, meaning "metal thread") and the suffix "-less" (from Old English -lēas, meaning "without"). Initially used to describe telegraphy without physical wires, it later expanded to radio communication and modern technologies like Wi-Fi. The morphemes reflect a straightforward negation: "wire" (the medium) + "less" (its absence).
