Morphology
captcha = C + A + P + T + C + H + A
This is an acronymic coinage from a longer phrase, so the written form does not transparently expose the meaning.
Etymology
Captcha comes from the phrase Completely Automated Public Turing test to tell Computers and Humans Apart, a long name made into a short word. It is like a tiny 'Turing test' on a website to prove you are a 'human' and not a 'robot', which is why CAPTCHAs stop automated spam.
