der Kai, -s

The German word "Kai" is a noun meaning "quay" or "pier" — a structure on the shore of a harbor where ships dock to load or unload cargo or passengers.

• "Kai" refers specifically to the landing stage or platform beside water.
• It is not broken down into smaller meaningful words (it's a standalone noun).

Similar words:

• Anleger (landing stage, jetty)
• Hafenmole (harbor mole/breakwater)
• Mole (pier)

Difference:

• "Kai" emphasizes the functional dock area for berthing ships.
• "Anleger" can be more general for any landing stage.
• "Mole" typically implies a breakwater or a larger pier structure that can also serve as protection from waves.
