Roman goddess of adult women and marriage, sister and wife of Jupiter, mid-14c., probably literally "the young one" (if so, perhaps as goddess of the new moon), from Proto-Italic *juwen- "young," which also is the source of Latin iunior "younger," iuvenis "young man" (see young (adj.)). Noted for her stately beauty and fits of jealous rage. Also the patron of national finances. Usually identified with Greek Hera, but Juno also had qualities of Athena.
word-forming element meaning "resembling or suggesting the style of," from French -esque "like, in the manner of," from Italian -esco, which, with Medieval Latin -iscus, is from Frankish or some other Germanic source (compare Old High German -isc, German -isch; see -ish).
