I’m not much of a fan of students using dictionary definitions to start a paper or to “prove a point.” Although I like it when a student uses a definition to give a sense of popular usage, that method is rare. Usually, students begin papers this way because they’re having trouble situating the topic within its historical context, and they are using the definition as a way to fill space instead of spending a few minutes to think about what they’re doing. Just as often, students are using definitions with the intent that “this is what the word means, and it only has this meaning.” This practice indicates that the student doesn’t understand how dictionaries are written or how the meaning of a word evolves.
Most publishers are not always concerned with accuracy in their definitions. Sometimes the definition in a dictionary merely uses the verb form to define a noun, such as “an advocate is a person who advocates.” If one does not understand what it means “to advocate,” one is not going to know what an “advocate” is. Because of the costs involved in publishing, publishers try to make the definitions as short as possible, trading brevity for accuracy. Moreover, their concern is for how the word is used in popular usage, but they sometimes need help in seeing that a definition is out-of-date or just inaccurate. In June of 2020, the New York Times reported that Merriam-Webster was updating its definition for racism, because they received a complaint about how it didn’t mention systemic racism.
As the above paragraph suggests, words are fluid. In fact, they change meaning and usage not only over time but also in different places. For example, the word “hussy,” generally used to indicate a woman of “loose morals,” comes from the Old English “huswife” which is in Modern English “housewife,” or a wife who takes care of the home. Additionally, the word “fantastic” originally meant that something was based in fantasy or created in the imagination. It is only in the past couple of centuries that people have used it to mean that something is “good” or “great.”
Also, when words are introduced into a new culture, the meaning of a word can be misunderstood, so that it is used in a different way. As an example, Koreans took the western words “apartment,” “condominium,” “house,” and “villa,” but apply them in different ways. Koreans generally live in large multi-family buildings, which usually range between ten and thirty floors tall. Since they buy these housing units outright, we should call them “condominiums.” Koreans call them “houses” or “apartments,” depending on the speaker. If the condominium building only rises three or four stories tall, Koreans call these “villas.” When Koreans rent a few rooms at a ski resort for a few days, they call this a “condominium.”
Even if you have not heard of Jacques Derrida, his philosophical works—which emphasize fluidity of language—have had an important impact on society as they are central to the concepts of deconstructionism and postmodernism. To make his point, Derrida uses puns, double-entendres, and sentences constructed to show just how ambiguous and fluid language is.
When academics utilize definitions in their works, they tend to do so in a couple of different ways. One method is to peruse dictionaries from various points in time in order to show how popular usage of words has changed so as to underscore how arguments about a topic have evolved. Another technique is to look at the specific ways in which a word has been used—and therefore defined—within particular primary and/or secondary sources so as to better elucidate distinct ideas associated with that word.
In this way, unless a student actually discusses how the definition of a word is important to their argument at various points in the paper, I consider the use of a definition at the beginning of the paper as an indication that it was written at the last minute and that its arguments are going to reflect a general lack of thought.
