Eurydice (also known as Eurydike) was a nymph in Ancient Greek mythology and the wife of Orpheus, who tried to bring her back from the underworld with the music of his lyre.
In Ancient Greek the name Eurydice means "wide justice", where eurys means "wide" and dike means "justice".
The correct pronunciation of Eurydice in English is Yuh-rid-ih-see. First, it's important to keep in mind that the first syllable, "Eu", is not pronounced with a "you" sound, but is more of a "yuh". Second, the end, "ce" is pronounced as -see, and you will often find this in other Greek names, where the "e" produces an "ee" sound.
