  - How to Meet 3.1.3 (Unusual Words)
  - Understanding Success Criterion 3.1.3 (Unusual Words)
- Success Criterion 3.1.4 (Abbreviations)

## Description

The objective of this technique is to provide the definition of words, phrases, jargon, or abbreviation expansions by adding a mechanism to access an on-line dictionary to the Web page. This technique uses existing resources on the Web to provide the definition rather than requiring the author to create a glossary or other mechanism within the site. By providing access from within the Web page, a user can easily locate the desired definition. This technique can only be used if the online dictionary returns the correct definition.

## Examples

### Example 1

A site that describes how a computer works would include a search form on each Web page. The search would be performed against an on-line dictionary of computer terms, acronyms, and abbreviations. Since the dictionary is specialized for computer terms, the acronym expansion found should be more accurate than with a general dictionary.

### Example 2

An online course in English grammar provides a paragraph of text which introduces new vocabulary words. Each of the vocabulary words is a link to an on-line dictionary to find the definition of the word. Activating a link will open up a new window to an online dictionary site with the specific vocabulary word defined.

1. Check that a mechanism exists within the Web page to search for the word, phrase, or abbreviation via an on-line dictionary.

2. Check that the result of the search of the dictionary for the word, phrase, or abbreviation the correct definition.

### Expected Results

- Checks #1 and #2 are true.

Note: The definition of abbreviation used in WCAG is : "shortened form of a word, phrase, or name where the original expansion has not been rejected by the organization that it refers to and where the abbreviation has not become part of the language."
