Forms
σείω (seíō) [1]
Etymology
It is inherited from Proto-Hellenic *tséihō,[1] inherited from Proto-Indo-European *twéyseti, from *tweys- (“to arouse, shock”).[1][2] The initial /s/ goes back to a consonant cluster, as the epic doubled /ss/ of ἐπισσείω (episseíō) and ἐσσείοντο (esseíonto) shows, and this allows the link with Sanskrit त्वेषति (tvéṣati, “to excite; to be excited, sparkle”).[3][4] Babiniotis describes the change as /tw/ > /ss/ > /s/.[5] Chantraine notes Wackernagel's objection that the Sanskrit verb is almost only middle and means “to be excited, blaze, shine”.[4] Forms without the /s/ of the root are found in Avestan 𐬚𐬬𐬀𐬫𐬀𐬵 (θvayah, “fright, danger”).[3][1] Beekes thinks that Σείριος (Seírios, “Sirius”) may be related.[3][5]
Earliest recorded meaning
It is found from Homer on, meaning to shake: warriors brandish their spears, a god shakes the aegis, horses shake the yoke, and in the passive a helmet quivers and the foothills of Ida quake.[6][7]
Semantic evolution
Herodotus uses it of earthquakes, which were attributed to Poseidon.[7] Pindar and Sophocles use it figuratively of gods or men shaking a city.[7] In Attic it also meant to blackmail, to frighten someone with false charges so as to extort hush money,[7] and its noun σεισμός (seismós) meant both an earthquake and extortion.[3] σεισάχθεια (seisákhtheia), the shaking off of burdens, was the name of Solon's law that cancelled debts.[3] The rattle called σεῖστρον (seîstron) passed into Latin as sistrum.[3]
The Septuagint uses it for shaking the earth and the heavens,[8] a passage that the Letter to the Hebrews quotes.[9] Medieval Greek had the forms σείζω (sízo) and σειώ (sió).[10] The word lives on as Modern Greek σείω (sío), to shake violently, especially of the earth in an earthquake.[11]
