To evacuate means to leave an area quickly, often because it's not safe to stay there. This could be because of a fire, flood, or other emergency.
When something big happens and people need to get out fast, we use the word "evacuate". Imagine you're at the beach and a strong storm warning comes on - the lifeguards might tell everyone to evacuate the area to stay safe from the wind and waves. In a city, if there's a fire in an apartment building, the firefighters will usually ask people to evacuate the building for their own safety.
We use "evacuate" with subjects like groups of people (e.g., "the family evacuated") or areas (e.g., "the city was evacuated").
To leave or withdraw from; to quit; to retire from
Example: The firefighters told us to evacuate the area as the flames approached.
