echolocate
C2Technical/Scientific
Definition
Meaning
To determine the position of objects by emitting sounds and listening for the echoes.
To navigate or locate objects using the biological sonar system employed by animals such as bats and dolphins.
Linguistics
Semantic Notes
A back-formation from 'echolocation'. Primarily an intransitive verb (the animal echolocates), but can be used transitively with objects like 'prey' or 'obstacles'.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Spelling remains consistent.
Connotations

Examples
By Part of Speech
verb
British English
- The pipistrelle bat can echolocate tiny insects in complete darkness.
- Researchers studied how the dolphins echolocate their prey in murky waters.
American English
- Bats echolocate by emitting high-frequency clicks.
- The study examined how whales echolocate over vast ocean distances.
adverb
British English
- This is not standard usage for 'echolocatingly'. Not used.
American English
- This is not standard usage for 'echolocatingly'. Not used.
adjective
British English
- The echolocating bat avoided the fine wires easily.
- They recorded the dolphin's echolocating clicks.
American English
- Echolocating species have highly specialized brain regions.
- The echolocating ability of the shrew is surprisingly sophisticated.
Examples
By CEFR Level
- Bats use sound to find food. (Implies concept, not the word.)
- Some animals, like bats, find their way using echoes.
- Dolphins and bats have the remarkable ability to echolocate, which helps them hunt in the dark.
- The research paper elucidates the neural mechanisms that allow juvenile bats to learn how to echolocate efficiently.
Learning
Memory Aids
Mnemonic
Think: ECHO + LOCATE = to locate something by using echoes, like a bat's built-in radar.
Conceptual Metaphor
SOUND IS A PROBE (emitting sound to 'feel' the environment).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'эхолот' (echosounder/fishfinder), which is a device. The verb is 'использовать эхолокацию' or, less commonly, 'эхолоцировать'.
Common Mistakes
- Using it as a noun (e.g., 'They use echolocate'). Confusing it with 'echo' alone. Incorrectly applying it to human-made radar systems.

FAQ
Frequently Asked Questions
No, it is a specialized term used primarily in scientific and technical contexts related to animal behavior.
In a limited way, yes. Some visually impaired individuals develop click-based echolocation to sense their surroundings, a skill studied under the term 'human echolocation'.
'Echolocate' refers specifically to the biological capability of living creatures. 'Sonar' (Sound Navigation and Ranging) is the human-engineered technological system based on the same principle.
The noun is 'echolocation'. 'Echolocate' itself is a verb, derived as a back-formation from that noun.
