Factolex Glossary

Description is a fact lexicon. We split up knowledge into small sentences: facts

You can use the data from Factolex to describe terms you are using in your blog posts or blog pages, and then place the glossary anywhere in your post using the shortcode [factolex].

Selecting terms for a post is easy: just click a button in the sidebar box and the plugin suggests terms to use. You can customize the definitions by creating an account at

Using the Factolex Glossary plugin does not require an account at

All the selected terms and explanations are stored in your WordPress database, so after selecting the terms from Factolex you are not dependent on it.

There seems to be a bad explanation for a term that I want to have in my glossary. How can I change that?

You can do this by creating your own lexicon at by clicking the checkboxes for facts that you find relevant. After you specify your username in the Factolex Glossary Settings the definitions are updated accordingly.

Will it degrade the performance of my blog?

This should not be a problem. All the data is cached in your local WordPress database.

Just when you browse your own blog (still logged on to your blog account), we refresh your own lexicon (if you have specified a username). This might cause some slowdowns, but those don’t happen for your users.

How can I customize the look and feel?

You can customize color, width and height through the Factolex Glossary Settings. If that’s not enough, you can also edit the file /wp-content/plugins/factolex-glossary/factolex-glossary.css. Be careful when updating the plugin. You could consider copying your changes into your theme CSS file.
