Making information about language accessible to users has long been a key concern of lexicographic research. Adopting a narrower perspective, this examination of three dictionary websites (collinsdictionary.com, merriam-webster.com, and dle.rae.es) employs the Web Content Accessibility Guidelines (WCAG) to examine their accessibility for people with visual impairments. Dictionaries can be motors for social inclusion of this oft-marginalised group since, beyond resolving language doubts, they can also help affirm socio-cultural identities. Unlike paper dictionaries where space-saving conventions make accessibility a challenge, in principle, online resources are adaptable to the needs of users with visual impairments. In practice, although none of the websites evaluated meet any officially recognised WCAG conformance level, they do contain features aimed at improving accessibility for this group. Most impediments to accessibility are the result of ancillary elements such as advertising, social media, games, and word of the day features. Although these ancillary elements may not necessarily be the principal focus of dictionary use, they nonetheless have a negative effect on the accessibility of the dictionary entry itself. This article concludes with suggestions for solving several of these accessibility issues.

在线词典和视障人士的辅助功能

长期以来，使用户可以访问有关语言的信息一直是词典编纂研究的一个关键问题。采用更狭隘的视角，对三个词典网站（collinsdictionary.com、merriam-webster.com 和 dle.rae.es）的检查采用 Web 内容可访问性指南 (WCAG) 来检查它们对视障人士的可访问性。字典可以成为这个经常被边缘化的群体融入社会的动力，因为除了解决语言疑虑之外，它们还可以帮助确认社会文化身份。与节省空间的惯例使可访问性成为挑战的纸质词典不同，原则上，在线资源可以适应有视觉障碍的用户的需求。实际上，尽管所评估的网站均未达到任何官方认可的 WCAG 一致性级别，它们确实包含旨在提高这一群体的可访问性的功能。大多数可访问性障碍是广告、社交媒体、游戏和每日新闻功能等辅助元素的结果。尽管这些辅助元素不一定是词典使用的主要焦点，但它们对词典条目本身的可访问性有负面影响。本文最后提出了解决其中几个可访问性问题的建议。然而，它们对词典条目本身的可访问性有负面影响。本文最后提出了解决其中几个可访问性问题的建议。然而，它们对词典条目本身的可访问性有负面影响。本文最后提出了解决其中几个可访问性问题的建议。
