Plain English Movement Around the World

In addition to the history of the Plain English Movement in the United States, at this time we can also take a look at the impact it has had in countries such as Canada, Australia and England.
Several books were written to encourage the use of Plain English. Among the most representative, we can highlight:
- Legal Writing: Sense and Nonsense, 1982, David Melinkoff
- The Fundamentals of Legal Drafting, 1986, Reed Dickerson
- A Dictionary of Modern Legal Usage, 1987, Bryan A. Garner

The most important general recommendations that we can take away from this literature are:
-  Use the greatest clarity possible;
-  Use examples;
-  Use easily readable font sizes;
-  Leave enough space in the margins;
-  Use tables and diagrams;
-  Divide the document into sections;
-  Place related paragraphs close to each other;
-  Sort the content in a logical sequence: the general before the specific, and the ordinary before the extraordinary;
-  Omit unnecessary details;
-  Include a summary in the first paragraph;
-  Assign one idea to each paragraph;
-  Use connectors;
-  Use short sentences, not more than 25 words;
-  Put the subject at the beginning of the sentence and near the verb;
-  Preferably use the active voice;
-  Use familiar words;
-  Avoid repetitions;
-  In technical documents for the public, explain specialized terms whose use is unavoidable;
-  Prevent abuse of negative constructions;
-  Always use the same term to refer to the same concept.
