union: union: [15] Union is one of a range of English words that go back to Latin ūnus ‘one’. This in turn was descended from a prehistoric Indo- European *oinos, which also produced English one. Other members of the family include inch, ounce, unique, unite [15], etc. As for union itself, its immediate ancestor was ūniō, a derivative of ūnus which denoted ‘unity’ or ‘the number one’. The application of the English word to an ‘association of workers’ dates from the early 19th century (a somewhat earlier term was combination).
