siren: [14] The Seirēnes were sea nymphs who, according to Greek mythology, sat on rocks luring impressionable sailors to their doom with the sweetness of their singing. Latin took the word over as sīrēna, and it passed into English via Old French sereine. The term was applied to an acoustical instrument invented in 1819 by Cagniard de la Tour, that produced musical sounds and was used for measuring the frequency of sound waves, and it was this that formed the basis of its later use (in the 1870s) for a device for giving loud warning signals.

Replaced Old English frið, also sibb, which also meant "happiness." Modern spelling is 1500s, reflecting vowel shift. Sense in peace of mind is from c. 1200. Used in various greetings from c. 1300, from Biblical Latin pax, Greek eirene, which were used by translators to render Hebrew shalom, properly "safety, welfare, prosperity."

siren (n.)youdaoicibaDictYouDict
mid-14c., "sea nymph who by her singing lures sailors to their destruction," from Old French sereine (12c., Modern French sirène) and directly from Latin Siren (Late Latin Sirena), from Greek Seiren ["Odyssey," xii.39 ff.], one of the Seirenes, mythical sisters who enticed sailors to their deaths with their songs, also in Greek "a deceitful woman," perhaps literally "binder, entangler," from seira "cord, rope."

Meaning "device that makes a warning sound" (on an ambulance, etc.) first recorded 1879, in reference to steamboats, perhaps from similar use of the French word. Figurative sense of "one who sings sweetly and charms" is recorded from 1580s. The classical descriptions of them were mangled in medieval translations and glosses, resulting in odd notions of what they looked like.
