Abstract:

The main objective of a controlled language is to make technical text easy to understand. Simplified Technical English standardizes vocabulary and style, aiming to improve consistency, eliminate ambiguity and reduce complexity. It also provides objective criteria for quality control. Simplified Technical English includes a general dictionary and a set of writing rules. In addition to the general vocabulary, companies can define their own Technical Names (terminology).
