Explaining complicated stuff using simple words

Book coverRandall Munroe’s latest book Thing Explainer will be released tomorrow. In the book, Munroe uses line drawings and only the thousand most common words to provide simple explanations for complicated objects.

It’s good practice to use words that are commonly understood. In some industries, Technical Authors have to write using only a limited list of approved words  (a “controlled vocabulary”). For example, there are controlled vocabularies for aircraft maintenance manuals, because some maintenance engineers have a only limited amount of English.

Sometimes, the word “stuff” doesn’t help the reader to understand. So what do you do when readers need to understand the small differences between objects, particularly when they can have a big effect on what happens next?

In order to write clearly, there are times when you need to use more than the thousand most common words. Technical Authors deal with this issue by using concept, terms and references topics. When they need to use words that some users might not understand, Technical Authors provide a link (or cross reference ) to another topic. This other topic provides an explanation or a definition of the word or concept. The topic can contain words, images, diagrams, animations or videos to help the user grasp the meaning.

It’s good to use simple words, but it’s more important to make sure the information is clear.
