Clanging

Clanging (also known as clang association) is a type of disordered speech characterized by choosing words for their sound instead of their meaning. A symptom of schizophrenia, clanging speech often rhymes or uses alliteration (words with the same initial sound- alive, alone, alike) when situationally inappropriate. An example would be the phrase, "There is my cat, mat, bat, rat, mattress, cactus."
