Forms

Leviathan m, indeclinable.[1][2]

Etymology

It is borrowed from Biblical Hebrew לִוְיָתָן (livyathan, “dragon, serpent, huge sea animal”),[3][4] a word of unknown origin, perhaps from a root meaning “to wind, twist”, with the notion of a serpent's coils.[3][4] The DMLBS classes it as Late Latin.[5]

Isidore of Seville explained it as “a serpent of the waters” and interpreted the name as “their addition”;[6] a gloss likewise renders it with a plural of additāmentum (“addition”).[7]

Earliest recorded meaning

It comes from the Latin Bible: the Vulgate has it in Job (3.8, 40.20), the Psalms (73.14, 103.26) and Isaiah (27.1),[8][4] for a fabulous monster, a twisting serpent, a dragon or a fearsome sea animal.[8]

Semantic evolution

Isidore identified Leviathan with Behemoth, the fallen angel made a beast, who “turns in the sea of this world with shifting cunning”.[6] In Medieval Latin the name stood for the sea monster of Job and Isaiah and, as a type, for Satan;[5][4] Köbler also gives the Nile crocodile.[4] Gervase of Tilbury calls a serpent “of the race of that most evil Leviathan, the serpent of the ocean”.[5]

English took the word in the late 14th century for a sea monster, sometimes seen as a form of Satan.[3]
