Diction and Syntax Diction Definition Diction can be defined as style of speaking or writing, determined by the choice of words by a speaker or a writer. Diction, or choice of words, often separates good writing from bad writing. It depends on a number of factors. Firstly, the word has to be right and accurate. Secondly, words should be appropriate to the context in which they are used. Lastly, the choice of words should be such that the listener or reader understands easily. Proper diction, or proper choice of words, is important to get the message across. On the other hand, the wrong choice of words can easily divert listeners or readers, which results in misinterpretation of the message intended to be conveyed. Types of Diction
