Controlled language is a simplified form of communication designed to reduce ambiguity and improve clarity. It uses a limited vocabulary and specific grammar rules to ensure that messages are easily understood by a wide audience. This approach is often employed in technical writing, user manuals, and international communication to minimize misunderstandings. One common example of controlled language is Simplified Technical English, which is used in the aerospace industry. By adhering to strict guidelines, writers can create documents that are more accessible to non-native speakers and individuals with varying levels of language proficiency, enhancing overall comprehension and safety.
