Etymology

CAPTCHA comes from an acronym for Completely Automated Public Turing test to tell Computers and Humans Apart, which means a test to tell 'computers' and 'humans' apart online. A helpful way to remember it is to think of 'catch a', like 'catch a bot', because a CAPTCHA tries to 'catch' robots and prove you are a person.
