Communication
Communication enables people to receive, express and use information across relationships, services and institutions.

Communication includes receiving, expressing and using information through context-appropriate means. The form can vary — speech, text, sign, assistive technology, digital systems — while the underlying functional requirement remains.
This domain sits at the intersection of human capacity and institutional design. A person can have strong communication capacity and still be excluded by inaccessible language, poorly designed forms, technical jargon or systems that assume a particular mode of interaction.
