Echolocation

Echolocation is a noun that refers to the location of objects by reflected sound. 

Our word of the day combines two words of Greek origin. Echo, which refers to the reflection of sound that occurs when sound bounces off a surface, and location, which means ‘place.’ Animals like bats that possess the ability to locate things without seeing, are skilled at echolocation. Here’s an example of its use:

Learning about bats at school was both fascinating and disappointing. It was fascinating to learn about the echolocation that these animals do because of their limited vision. But it was disappointing to not learn anything about Batman.
