bar-coded

The word is a modern compound adjective formed in the late 20th century. Its first element, 'bar', draws on its sense of a long, straight, narrow strip, which visually describes the parallel lines of a barcode. The second element, 'code', originates from the Latin codex, referring to a system of laws or symbols for recording information. The suffix '-ed' is added to indicate the state of being marked with such a code. Thus, the term's literal logic is "characterized by having a strip-based symbolic system," which perfectly captures the technology's function of encoding data in a pattern of varying-width bars for optical scanning.

Structure: bar (strip) + code (system of symbols) + ed (adjective suffix) - bar: From Old French barre (beam, barrier, strip), of uncertain origin, possibly from Vulgar Latin barra. In this compound, it functions as a modifier meaning a straight, narrow strip. - code: From Old French code, from Latin codex (a book, a wooden tablet). In this compound, it functions as the core noun meaning a system of symbols for communication. - ed: From Old English -ede, -od, -ad, a suffix forming adjectives from nouns or verbs, indicating possession or being characterized by something.
