Abstract:

The increase in the number of products with accompanying documentation sold around the world has shown the need to develop some form of controlled English guideline. Simplified English is just one type of controlled English. The apparent benefits of writing in controlled fashion has led some to consider it a panacea. Others, however, have urged caution in accepting controlled English as the solution to all problems in the comprehension of documents. All forms of controlled English have certain essential features that any technical writer can accept.
