A

Accommodation

A change, adjustment or support that helps reduce a barrier so a person can participate more fairly or effectively. Accommodations may relate to communication, timing, environment, equipment, information or how a task is completed.

Related: Reasonable adjustment, Accessibility, Barrier

Accessibility

The extent to which environments, information, services, technology and activities can be reached, understood and used by people with different needs and abilities. Good accessibility aims to reduce unnecessary barriers from the beginning.

Related: Universal design, Inclusion, Participation

Accessible Format

A way of presenting information so it can be used by people with different access needs. Examples can include large print, captions, plain language, Easy Read, audio, Braille or accessible digital documents.

Related: Communication access, Digital accessibility

Advocacy

Speaking up, taking action or supporting someone to have their needs, rights and views heard. Advocacy can be done by a person for themselves or with help from another person or organisation.

Related: Self-advocacy, Independent advocacy

Assistive Technology

Technology, equipment or software that helps a person complete tasks, communicate, access information or participate more independently. Examples can include screen readers, speech-to-text tools and alternative input devices.

Related: Digital accessibility, Accommodation

B

Barrier

Something in an environment, system, attitude, process, communication method or design that makes access or participation harder. Barriers can be physical, sensory, digital, communication-based, organisational or attitudinal.

Related: Accessibility, Discrimination

Built Environment

The human-made spaces where people live, work, learn and take part in community life, including buildings, entrances, paths, facilities and public spaces. Accessibility in the built environment considers how different people can enter, move through and use those spaces.

Related: Physical accessibility, Universal design

C

Captioning

Text that represents spoken words and important sounds in video or live communication. Captions can support Deaf and hard-of-hearing people and can also help people who process information more easily through text.

Related: Communication access, Digital accessibility

Communication Access

Making communication understandable and usable for people with different communication, language, sensory or processing needs. This can include extra processing time, written information, captions, interpreters, visual supports or alternative communication methods.

Related: Accessible format, Accommodation

Complaint

A formal or informal way of raising a concern about a service, decision, treatment, barrier or possible rights issue. Complaint processes differ between organisations, countries and legal systems.

Related: Discrimination, Remedy, Advocacy

Consent

Freely agreeing to something after receiving enough understandable information to make a choice. In accessibility contexts, communication and decision-making support may be important so consent is genuinely informed.

Related: Supported decision-making, Communication access

D

Digital Accessibility

Designing websites, apps, documents and digital services so people with different disabilities and access needs can perceive, understand, navigate and use them.

Related: WCAG, Assistive technology, Accessible format

Disability

A broad term that can describe physical, sensory, intellectual, learning, neurological, mental health or other long-term impairments and access needs. Different laws, communities and individuals may define or understand disability in different ways.

Related: Social model of disability, Neurodiversity

Discrimination

Unfair or unequal treatment connected with a protected characteristic or other legally protected ground. The exact legal definition, tests and remedies depend on the law that applies in a particular place.

Related: Equality, Complaint, Human rights

E

Equal Opportunity

A principle that people should have a fair chance to participate, access services and pursue opportunities without unjustified barriers or discrimination. Fair access may require different supports rather than identical treatment.

Related: Equality, Equity, Accommodation

Equality

The principle that people should have equal rights, dignity and protection. In practice, equality does not always mean treating everyone in exactly the same way when different barriers or needs exist.

Related: Equity, Human rights, Equal opportunity

Equity

An approach focused on fairness by recognising that people can face different barriers and may need different resources or supports to have a genuinely fair opportunity to participate.

Related: Equality, Accommodation, Inclusion

H

Human Rights

Fundamental rights and freedoms that protect dignity, equality and participation. Human-rights protections can come from constitutions, legislation, treaties and other legal frameworks, and their exact application varies by jurisdiction.

Related: Equality, Discrimination, Remedy

I

Inclusion

Creating environments and communities where people are welcomed, respected and able to participate meaningfully. Inclusion involves more than simply being present; it includes having genuine access, belonging and opportunity.

Related: Participation, Accessibility, Belonging

Independent Advocacy

Advocacy support provided by a person or organisation whose role is to help someone express their views, understand choices or protect their rights without being controlled by the service or authority involved in the issue.

Related: Advocacy, Self-advocacy

Informed Choice

Making a decision after receiving enough relevant information in a form that can be understood. Accessible communication and adequate time can be important parts of informed choice.

Related: Consent, Supported decision-making

L

Legal Right

A right recognised and protected by law. Legal rights vary between countries and regions, and the exact wording, coverage, exceptions and enforcement processes depend on the law that applies.

Related: Human rights, Remedy, Complaint

N

Neurodivergent Accessibility

Accessibility that recognises differences in sensory processing, communication, attention, executive functioning, learning, predictability needs and ways of participating. The aim is to reduce unnecessary barriers rather than require everyone to function in one standard way.

Related: Accommodation, Sensory accessibility

Neurodiversity

The idea that human brains and nervous systems naturally vary. Neurodiversity includes many different ways of thinking, learning, communicating and processing information.

Related: Neurodivergent accessibility, Inclusion

P

Participation

Being able to take part meaningfully in education, work, services, community life, relationships and decision-making. Accessibility supports participation by reducing barriers.

Related: Inclusion, Accessibility

Plain Language

Communication written or spoken in a clear, direct way that makes information easier to understand. Plain language can improve accessibility but is not the same as Easy Read, which uses additional structure and visual support.

Related: Accessible format, Communication access

R

Reasonable Adjustment

A change intended to reduce a disadvantage or barrier for a disabled person. The legal meaning and the factors used to decide what is reasonable differ between jurisdictions, so official local guidance should be checked when the term is used legally.

Related: Accommodation, Accessibility

Remedy

An outcome intended to address a rights violation, unfair treatment or harm. Depending on the system, remedies might include changing a decision, providing access, correcting a process, compensation or another form of resolution.

Related: Complaint, Discrimination, Legal right

S

Self-Advocacy

Understanding and expressing your own needs, preferences, choices and rights. Self-advocacy can include asking questions, requesting support, preparing for meetings and speaking up when something is not accessible.

Related: Advocacy, Informed choice

Sensory Accessibility

Reducing avoidable sensory barriers involving sound, lighting, touch, smell, movement, crowding or other sensory input. Sensory accessibility can include quieter spaces, predictable environments and options for different ways of participating.

Related: Neurodivergent accessibility, Accommodation

Social Model of Disability

An approach that focuses on the barriers created by environments, systems and attitudes rather than viewing disability only as a problem located within an individual. It highlights the role of removing barriers and improving access.

Related: Barrier, Accessibility, Inclusion

Supported Decision-Making

An approach in which a person receives the support they need to understand information, consider options and communicate decisions while keeping their own voice, preferences and choices central.

Related: Informed choice, Consent

U

Universal Design

Designing environments, products, services and information so they can be used by as many people as possible from the outset, rather than relying only on individual fixes after barriers appear.

Related: Accessibility, Built environment

W

WCAG

Web Content Accessibility Guidelines: internationally used guidance for making web content more accessible to people with disabilities. WCAG includes principles and testable success criteria used in many digital-accessibility policies and standards.

Related: Digital accessibility, Assistive technology

From Definition to Everyday Meaning

A definition becomes most useful when it helps you recognise a barrier, understand an option or explain what could make participation easier in real life.

From Definition to Everyday Meaning infographic connecting accessibility terminology with everyday examples and more inclusive participation.
Remember: the same word can have a broad everyday meaning and a narrower legal, policy or service definition. If the exact definition affects your rights or a formal decision, use the current official wording for your country, region or organisation.

Clearer words can make the next step easier.

You do not need to learn every term at once. Use this glossary when a word appears, follow the related pathway when you need more detail, and return whenever you need a clearer starting point.
