How to Create an Effective WordPress Multilingual Glossary
One of the more important tools on any website, that is often overlooked, is a glossary. A glossary can include a full list of helpful terms on your website. The glossary can also be in different languages.
The Tooltip Glossary plugin creates an index page that lists every term needed, automatically. This list is usually alphabetical, and the terms that appear on different pages have tooltips that appear on mouseover.
