English

A typical representation of a CAPTCHA

Etymology

Coined by a team of researchers at Carnegie Mellon University in 2000 as a loose acronym of "Completely Automated Public Turing test to tell Computers and Humans Apart".

Noun

CAPTCHA (plural CAPTCHAs)

  1. A computerized test requiring the human user to perform a task deemed to be difficult to automate, such as entering a displayed series of distorted characters or describing images, to demonstrate that he/she is a human and not a computer program.

Usage notes

Although occasionally spelt with lowercase letters (captcha), or with an initial uppercase letter (Captcha), most authors remain aware of its origin as an acronym and use uppercase. This is not always the case for other languages. For example, the Dutch language has adopted the word from English, but only in its anacronym form. Thus in Dutch it is spelled with lowercase letters.
