thalassa denotes the sea as a body of water, including its shores, crossings, waves, and named waters.

The term consistently denotes a body of water: people stand beside it, travel across it, cast things into it, and encounter its waves or wind-driven motion. The same referent appears in named-water settings, creation language, comparison, and the scene where it gives up its dead.

1. The sea as a body of water · dominant

   Across accusative, genitive, dative, and nominative singular forms, the term names the body of water beside which people gather or fish, as in Mark 1:16, and across which boats travel, as in John 6:17. In John 6:18 the nominative singular form is the water stirred by a strong wind; in Acts 27:38 grain is thrown into it, while Acts 14:15 includes it among what God made. James 1:6 uses its wave in a comparison, and Revelation 20:13 describes it as giving up the dead in it.

In the Anselm Project Bible: The APB commonly presents the term as “sea” in settings of travel, shoreline activity, waves, and creation; Hebrews 11:12 has “seashore” in the phrase about sand beside it. These renderings confirm the verse contexts rather than establish separate meanings.
