Accessibility
Plain-language definitionThe practice of making products usable by people with a broad range of abilities, technologies, and contexts. It includes perception, operation, understanding, and compatibility.
Why it matters
Use the term to make a better decision.
In practice, accessibility matters when a team needs to connect a technical or creative choice to a visible change in clarity, performance, discovery, or conversion. The useful question is not whether the term sounds sophisticated. It is what decision it helps the team make.
