Why is dialogue not a characteristic of functional text?

Functional texts are usually designed to fulfill specific purposes and provide information to users to achieve a certain goal or outcome. These texts are generally precise, concise, and straightforward, conveying information in a direct and objective manner. Dialogue, on the other hand, involves two or more people engaging in a conversation, expressing opinions and emotions, and exchanging information.

Functional texts such as manuals, forms, instructions, and technical reports are not intended to create a conversation or emotional connection with the reader but instead aim to provide information in a clear and concise manner. Therefore, dialogue is not a characteristic of functional text as it does not serve the purpose of these kinds of texts.
