Etymology
the word 'echolocation' is a modern scientific compound, first used in the mid-20th century. it is constructed from the greek-derived word 'echo,' referring to a reflected sound, and the latin-derived combining form 'loc,' from 'locus' meaning place, combined with the noun-forming suffix '-ation.' the term literally means "the process of locating by echo," directly and logically describing the biological sonar system. this neologism elegantly combines classical roots to create a precise technical term, where 'echo' provides the sensory mechanism and 'location' specifies the functional outcome, perfectly capturing the essence of the animal's navigational ability.

bats are renowned for their use of echolocation to navigate and hunt in complete darkness.
the study of dolphin echolocation has inspired advancements in human sonar technology.
some blind humans can learn a form of echolocation by making clicking sounds and listening to the returning echoes.
