What is the origin of sirenic?
English Siren (the mythical creature) comes from Greek Seirḗn, which has no reliable etymology. The Sirens first occur in the The Odyssey (book 12); there are only two of them, they are unnamed, and they live on an island yet sit in the middle of a flowery meadow surrounded by the moldering bones of the mortals they have beguiled. What the Sirens tempt Odysseus with is knowledge, irresistible for the curious, restless hero: “We know everything that happened at Troy, what the Argives (Achaeans, Greeks) and Trojans suffered at the will of the gods, and we know everything that happens on the all-nourishing earth.” Homer says nothing about the physical appearance of the Sirens—nothing about birds with the torso and arms of a woman, how many Sirens there were, their names and genealogy, all of which are later additions. The suffix -ic, however, has an excellent etymology: it comes from the Proto-Indo-European adjective suffix -ikos. The Greek form of this suffix is -ik ós, in Latin -icus (-ique in French). English -ic may come from the Greek, Latin, or French forms.
