Words related to business

busy (adj.)
Old English bisig "careful, anxious," later "continually employed or occupied, in constant or energetic action" cognate with Old Dutch bezich, Low German besig, but having no known connection with any other Germanic or Indo-European language. Still pronounced as in Middle English, but for some unclear reason the spelling shifted to -u- in 15c.

The notion of "anxiousness" has drained from the word since Middle English. Often in a bad sense in early Modern English, "prying, meddlesome, active in that which does not concern one" (preserved in busybody). The word was a euphemism for "sexually active" in 17c. Of telephone lines, 1884. Of display work, "excessively detailed, visually cluttered," 1903.

word-forming element denoting action, quality, or state, attached to an adjective or past participle to form an abstract noun, from Old English -nes(s), from Proto-Germanic *in-assu- (cognates: Old Saxon -nissi, Middle Dutch -nisse, Dutch -nis, Old High German -nissa, German -nis, Gothic -inassus), from *-in-, originally belonging to the noun stem, + *-assu-, abstract noun suffix, probably from the same root as Latin -tudo (see -tude).

pidgin (n.)

1876, "artificial jargon of corrupted English with a few Chinese, Portuguese, and Malay words, arranged according to the Chinese idiom, used by the Chinese and foreigners for colloquial convenience in business transactions in the ports of China and the Far East," from pigeon English (1859), the name of the reduced form of English used in China for communication with Europeans, from pigeon, pidgin "business, affair, thing" (1826), itself a pidgin word (with altered spelling based on pigeon), representing a Chinese pronunciation of business. The meaning was extended by 1891 to "any simplified language."
