Definition decision workflow

2. Test the nearest option

Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.

Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.

Final meaning check

Before publishing a sentence with "leviathan", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.

When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

Etymology

The noun is derived from Middle English leviathan, levyathan, levyethan, from Late Latin leviathan, a transliteration of Biblical Hebrew לִוְיָתָן (liwyāṯān), possibly from לִוְיָה (liwyâ, “garland, wreath”) + ־תָּן (-tān, suffix forming agent nouns), literally “the tortuous one”. Noun sense 2.2 (“political state”) was coined by English philosopher Thomas Hobbes (1588–1679) in his work Leviathan (1651): see the quotation. Noun sense 2.3 (“synonym of Satan”) refers to Isaiah 27:1 in the Bible (King James Version, spelling modernized): “In that day the Lord with his sore and great and strong sword shall punish Leviathan the piercing serpent, even Leviathan that crooked serpent, and he shall slay the dragon that is in the sea.” The adjective is from an attributive use of the noun.
