Knowing a lot of words is important, but just as important is knowing how to use them.
The body of words you know and understand is called “vocabulary.” The practice of choosing how to use those words is called “diction.” Both are important, but in different ways. Vocabulary is important as a body of knowledge. Diction is important as an activity you practice.
Of course, vocabulary is the foundation of writing. In order to write, you need a body of knowledge about words: a vocabulary. This large body of knowledge is the first sense in which vocabulary is important.
However, vocabulary is important in a second sense, too. The word, “vocabulary” has a more specific use. Subjects and disciplines have words that are specific to them. When you write about a subject or participate in a discipline, these vocabularies are important to learn. They fall into two categories.
Sometimes subject and discipline-specific vocabularies consist of words you have never (or seldom) heard. They are not commonly used. We call these words “jargon.”
Jargon can be off-putting, vague, or worse, pretentious. Although no discipline or subject is immune, some of the most frequently discussed examples come from business settings:
The word “synergize” is jargon for coordinating, working together, or combining efforts. However, one just as easily could use coordinate, cooperate, or collaborate. These words have the benefit of being commonly understood and precise.
The word “leverage” is a noun that signifies the act of moving something using a lever. In business settings, however, "leverage” is often used more broadly as a verb. “Let’s leverage our resources.” However, one just as accurately, and more accessibly, could say, “Let’s use our resources.”
There are times, however, when jargon is shorthand for people in a hurry. This can be true, for example, in medical settings.
Writing or saying “atypical” substitutes for “That does not usually happen.”
Writing or saying, “The patient has comorbidities,” substitutes for “The patient is suffering from two or more illnesses at the same time.”
In these cases, jargon eliminates wordiness and gets right to the point.
Sometimes subject and discipline-specific vocabularies consist of words you have heard before. The difference is that these words have specific meanings within a particular subject or discipline. Sometimes these uniquely used words are shortened forms of longer words. Other times they are merely common words used with a slightly different meaning.
When most people use the word “script,” they usually mean writing or the written form of a play or movie. However, in a medical setting, "script” is short for a prescription.
When most people speak of an “engagement,” they usually mean a planned event or a commitment to marry another person. However, in tech settings, “engagement” signifies audience interaction with a creative product.
When you write, you make choices—about which words to use, about the order in which you will use them. We call these choices “diction.” These choices are consequential, especially for tone and voice. However, diction is also consequential for clear, nuanced, and complex exploration of ideas.
Consider the following two statements, both from a current college student:
The film was quite good.
The filmmakers superbly introduced their story and characters, and despite a three-hour runtime, the film never dragged on, which was in part due to stunning visuals, solid acting, and a soul-wrenching score.
Both statements communicate a positive opinion. Both are reasonably formal in tone. However, notice how vague the first statement is. “Quite good” could have any number of unstated meanings. The goodness of the film remains a mystery. Improved diction helped unpack “quite good” for the reader.
Notice in contrast the precise language of the second example. We now know what the writer appreciated about the film. Notice also the vivid adjectives: “stunning,” “solid,” and “soul-wrenching.” These draw the reader into how the author feels about the film. Finally, notice how the author uses categories specific to popular film criticism: “dragged on” (i.e. pacing), “visuals,” “acting,” Competent diction provides complexity and clarity.
