theme: Wording
How language, tone, and phrasing impact accessibility.
3.1.4 Abbreviations
Abbreviations and acronyms should be avoided when possible, or explained the first time they appear.
3.1.5 Reading Level
If content requires reading skills above lower secondary education (around 9th grade), provide a simpler version, a summary, a visual aid, or a spoken version to help with understanding.
3.1.6 Pronunciation
If a word can be pronounced in different ways with different meanings, the intended meaning must be clarified to avoid confusion or ambiguity.
3.3.1 Error Identification
Errors and validation must be clearly identified and described in text, not just visually (like color or highlighting).
3.3.3 Error Suggestion
Errors and validation messages must show text that explains the problem and gives suggestions for how to fix it (like “enter at least 8 characters”).

Before submitting important actions (like payments or legal forms), the form must allow reviewing the input, correcting mistakes, or confirming.
3.3.5 Help
Provide additional help (like text instructions, help links, or tooltips) when label alone might be ambiguous or confusing.
3.3.6 Error Prevention (All)
Before submitting, all forms must allow reviewing the input, correcting mistakes, or confirming.
