The sea is the large body of salty water that covers much of the Earth’s surface; it can also mean a specific part of the ocean.
From Old English “sæ,” from Proto-Germanic “saiwiz,” all meaning “sea” or “lake.” It is one of the oldest nature words in Germanic languages.
We sometimes talk about “the sea” and “the ocean” as different things, but they’re really one connected global water system. The borders we draw on maps don’t mean much to the water itself.
