Complex verbal tics can include echolalia, which is repeating the last word or phrase that they heard from others, palilalia, which is a repetition of a person's own words or phrases, or coprolalia, which is saying inappropriate words or obscenities.
Palilalia (from the Greek πάλιν (pálin) meaning "again" and λαλιά (laliá) meaning "speech" or "to talk") a complex tic, is a speech disorder characterized by the involuntary repetition of syllables, words, or phrases. It has features resembling other complex tics such as echolalia or coprolalia, but unlike other aphasias, palilalia is based upon contextually correct speech.
