Meaning & History
Probably derived from the Greek noun ὄρος (oros) meaning "mountain, hill" (compare Orestes) combined with the Greek noun ἄνθος (anthos) meaning "flower". Also compare the similar-looking name Orinthia, which can even be an anagram of Orianthi, if you move the letters around a bit.This name is best known for being the name of the Australian singer-songwriter Orianthi Panagaris (b. 1985), who is of Greek descent.
