Tsunami

The word tsunami comes from Japanese. It combines tsu, meaning “harbour,” and nami, meaning “wave.”

Japanese fishermen used the word because large ocean waves sometimes caused destruction in harbours even when the sea looked calm offshore.

The word entered international English vocabulary through science, geography, news reporting, and natural disaster discussions.

Today, tsunami is widely used in conversations about earthquakes, oceans, climate, and emergency events.

For ESL learners, tsunami is useful in geography, science, environment, and news-related vocabulary.

Tsunami (noun) is a very large and powerful ocean wave usually caused by an underwater earthquake, volcanic eruption, or landslide.

Tsunamis can travel across oceans and cause severe flooding and destruction when they reach land.

Example: The tsunami damaged many coastal towns.

Example: Scientists issued a tsunami warning after the earthquake.
