Juno was the Roman goddess of women and marriage, and the wife of Jupiter. Her name is of uncertain origin, but could well derive from the root of juvenis, 'young', in the sense of 'young bride'. On the other hand, her name may somehow link up with that of Jupiter, although one would expect a form Diuno or something like it, and there are no such names recorded.

Somewhat curiously, the English adjective 'Junoesque', derived from her name, came to change its meaning in the latter half of the twentieth century from 'having stately bearing and regal beauty' to simply 'stout', 'well-built', especially in the phrase 'a Junoesque figure'.
