<unk>  (from the Greek πάλιν (pálin) meaning "again" and λαλιά (laliá) meaning "speech" or "to talk"), a complex tic, is a language 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,<unk>  is based upon contextually correct speech. It was originally described by Alexandre-Achille Souques in a patient with stroke that resulted in left-side hemiplegia, although a condition described as auto-echolalia in 1899 by Édouard Brissaud may have been the same condition.
