Diction refers to the correct use of words when speaking or writing in a given language. Good diction means using words properly without regard to meaning. Diction comes from the Latin word for "way of speaking". When speaking or singing, it is essential to avoid vices or defects in diction, which can interfere with communication. There are about 25 vices of diction, including vulgarisms, barbarisms, cacophonic hiatus, solecism, dequeism, cacophony, monotony, amphibology, and cosism. Placement of the voice and diction are important for producing sound correctly.
