Clear Meaning

Goal

To help people understand text:

This guideline covers four types of ambiguous text content:

For each instance of ambiguous text content, the goal is to ensure clarity and provide necessary context.

Making ambiguous content (including non-literal or figurative language) easier to understand helps people with cognitive disabilities as well as neurodivergent people, such as those who are autistic and may be so focused on the literal meaning that they may not notice the implied meaning.

Explaining or avoiding ambiguous language can also help:

Normative text

Guideline

Users can access explanations of or alternatives to ambiguous text content.

Foundational Requirements

For each item of ambiguous text, such as non-literal text, abbreviations and acronyms, ambiguous numbers, or text missing letters or diacritics:

  1. Is the ambiguous text presented in a way that is available to user agents, including assistive technology (AT)?
    1. Yes, view meets Text is programmatically determinable, continue.
    2. No, continue to step 3.
  2. Does the accessibility support set meet Explain ambiguous text or provide an unambiguous alternative?
    1. Yes, pass. Stop.
    2. No, continue.
  3. Does the author meet Explain ambiguous text or provide an unambiguous alternative?
    1. Yes, pass. Stop.
    2. No, fail.

Exceptions

  • If the purpose is to showcase works of art or fiction, such as a poetry journal or fictional stories, this guideline does not apply; however, if the purpose is to educate students about pieces of art, then this guideline applies.

Supplemental Requirements

None defined at this time.

Assertions

There will probably be a generic assertion based on style guides that applies to this guideline.

What to do

Determine if the text has words or phrases that:

  • Hint at a meaning that is not directly stated, or
  • Can have more than one meaning, such as working on a literal and figurative level at the same time. Example in English: “The chef cuts corners when slicing the fish.” Non-literal: The chef is preparing the fish in an easy or cheap way. Literal: The chef is cutting the fish into shapes that don’t have sharp corners.

When checking for ambiguous text, also consider how sentences are combined together, such as if a word in one sentence is critical to accurately understanding the meaning of a later sentence.

If the text has implied meaning, explain it or provide an unambiguous alternative using one of the techniques in the Methods section.
