IPA: /ləˈɡuːn/
KK: /ləˈɡun/
A shallow area of water that is often separated from a larger body of water by sandbars or coral reefs.
The tropical island was surrounded by a beautiful lagoon filled with colorful fish.
Lagoon originates from the Italian word 'laguna', which comes from Latin 'lacuna', meaning a pool or pond. The word describes a shallow body of water separated from a larger body of water, often by a barrier such as a sandbank or coral reef.
Imagine a 'pool' ('lacuna') of water that is 'separated' from the ocean, which helps you remember that a lagoon is a shallow body of water.
