Chapter Objectives: 1. Differentiate the forms of technical writing. 2. Explain principles involved in writing classification, process, definition, and description of a mechanism. 3. Apply the principles learned by applying them in writing.
Four Expository Techniques Classification D efinition Description of a process Description of a mechanism
“In the old days, you would have one lawyer to handle everything: speeding tickets, buying a house, contracts, litigation, real estate, copyrights, leasing, entertainment, intellectual property, forensic, accounting, criminal offenses… the list goes on. Now, you have to have a separate lawyer for each one of those categories!” – James Belushi
Classification is dividing something into groups, classes, categories, etc. This is normally done in accordance with several criteria (standards or principles on which judgments are based). 1.Classification Classification is done by the writer when he/she believes that there are shared qualities or characteristics about a subject matter.
“Without words, without writing and without books there would be no history, there could be no concept of humanity.” – Herman Hesse
2. Definition When we define words or unfamiliar terms, we give concise but exact meanings of unfamiliar and familiar words. Definition is useful in oral or written communication and is a must for a technical writer.
Methods of Defining Terms Simple and Expanded
A simple definition could be formulated by bearing in mind its three parts: the species, genus, and differentia. This method of definition is commonly used in technical writing whether formally, semi-formally, or non-formally.
Example: “Communication is a systematic process in which people interact with and through symbols to create and interpret meanings.” A expanded definition is done by stipulation, operation, explication, cause and effect, classification, example, and other rhetorical functions. Communication (species) is a systematic process (genus) in which people interact with and through symbols to create and interpret meanings (deffirentia)
Informal definition does not follow a strict pattern. It explains unfamiliar words or the special meaning of familiar ones by using denotation (literal or dictionary meaning) and connotation (the positive or negative associations a word carries). Examples: Denotation: Draft is the first version of a written work. Connotation: Draft implies something unfinished but open for improvement. Denotation: Feedback is a response or comment about one’s work. Connotation: Feedback often suggests guidance, support, or even criticism for growth.
“Writing the perfect paper is a lot like a military operation. It takes discipline, foresight, research, strategy, and, if done right, ends in total victory.” –Ryan Holiday
3. Description of a Process Description of a process is a type of writing that explains how something works, is done, or made. It may provide instructions on (how to do something) or explain the sequence of events on (how something occurs). It helps both the writer and the reader understand or perform a task clearly. Presents steps in chronological order Often uses the present passive tense (e.g., is manufactured, is prepared) Makes use of sequence markers like first, next, then, finally
3. Description of a Process Example: “Making a cup of coffee is a simple process. First , hot water is boiled. Next , coffee grounds are placed in a cup. Then , the hot water is poured over the grounds. Finally , sugar and milk are added before the drink is stirred and served”.
“If a writer knows enough about what he is writing about, he may omit things that he knows. The dignity of movement of an iceberg is due to only one ninth of it being above water.” – Ernest Hemmingway
4. Description of Mechanism Description of a mechanism is an e xplanation of a system or parts of an apparatus. This includes the characteristics and functions of a piece of the device and the totality of the mechanism. In writing a description of a mechanism, the writer may be guided by the following questions: ➢ What is it (equipment, machine, device, apparatus)? ➢ What is its function? ➢ What does it look like? ➢ How does it work? ➢ What are its principal parts?
4. Description of Mechanism Example: 🖊 Ballpoint Pen What is it? A writing instrument. Function: Writes using ink. Appearance: Cylindrical body, cap/clicker. How it works: Ink flows to the tip when pressed. Parts: Barrel, ink cartridge, tip, cap/clicker.
Conclusion Exploring expository techniques helps writers present information clearly and logically. Using definition, process, and mechanism descriptions, technical writing becomes more effective in explaining ideas, guiding actions, and enhancing understanding.
