Middle English Mouse Dictionary от CB

You can double-click or select Middle English HTML text, and, If the words are in the dictionary, a small popup will appear next to your mouse with information about the word. You can click the (+) button to add it to your personal words sidebar, which is stored for each page. You can open the dictionary by right-clicking and selecting the "Open Sidebar" option.

At present our dictionary is small, and future updates to this extension will broaden the vocabulary available and include greater functionality.
