Podcast 1 — Introduction & meaning

Narrator: Today's word is "Sea" — noun, pronounced /siː/, with the stress on "sea".

Narrator: The sea is the expanse of salt water that covers most of the earth's surface.

Narrator: In plain English, the sea is the ocean — the vast body of salt water you see at the coast.

Narrator: It comes from the Old English sǣ, meaning a sea or lake, of Germanic origin.

Narrator: "The open sea" describes the ocean far from land, where no coast is visible.

Narrator: It differs from ocean because sea is more general and can be partly enclosed, whereas ocean is the vast open expanse.

Narrator: "A sea of faces" is a figurative sense meaning a large crowd seen from a distance.

Narrator: Geography, sailing, tourism, weather and literature all rely on the word sea.

Narrator: So remember: the sea is the salt-water expanse, from the Old English sǣ.

Podcast 2 — In conversation

Speaker A: What is the sea?

Speaker B: The salt-water expanse! SEA comes from the Old English sǣ, so it means the vast body of salt water covering most of the earth.

Speaker A: So the sea and ocean are the same?

Speaker B: Nearly — sea is more general, ocean is the open expanse!

Speaker A: Example sentences?

Speaker B: "The open sea"; "a sea of faces"; "at sea" — ocean, crowd and confusion.

Speaker A: Common mistakes?

Speaker B: Don't confuse sea with see, because sea is the body of water, while see means to look.
