Disability and Accessibility Vocabulary in English

Accessibility is the general quality or goal of making something usable for everyone, including disabled people. Accessible describes a specific place, product, or service that already meets that standard, such as an accessible building with ramps and wide doorways.

A mobility aid specifically helps someone move around, such as a cane, walker, or wheelchair. Assistive technology is a broader term covering any device or software, including screen readers and communication apps, that helps a disabled person perform tasks more easily.

A reasonable adjustment is a practical change, such as flexible hours or accessible software, made so a disabled employee is not put at a disadvantage compared to colleagues. Employers in many countries are legally required to consider these adjustments.

Hearing impairment is a general term for any reduced ability to hear, ranging from mild to severe. Many people who are profoundly deaf identify with Deaf culture and use sign language as their first or preferred language rather than viewing deafness only as a medical condition.

A screen reader converts on-screen text into speech, letting someone navigate a computer or phone by listening. Braille instead uses raised dots that are read by touch, commonly found on signs, packaging, and dedicated Braille displays.

Neurodivergent describes someone whose brain processes information differently from what is considered typical, including conditions such as autism, ADHD, or dyslexia. It is a respectful, widely used term that focuses on natural variation rather than deficit.

A barrier-free building has no physical obstacles, such as steps or narrow doorways, that would stop a wheelchair user or someone with a mobility aid from moving through it freely. Ramps, wide corridors, and accessible parking are common features.

Universal design means building a product or space to work for the widest range of people from the very beginning, rather than adding accessibility features afterward. A building with universal design might have step-free entrances everywhere, benefiting wheelchair users, parents with buggies, and delivery workers alike.

This vocabulary helps you talk respectfully and accurately about disability, understand accessibility signs and information, and follow news or workplace discussions about inclusion. Words like accessible, ramp, and closed captions appear often in public spaces and everyday services.

Start with everyday essentials: accessible, wheelchair user, ramp, sign language, and inclusion. Once these feel natural, add more specific terms such as reasonable adjustment, assistive technology, and universal design to discuss accessibility in more depth.
