This extension is great for doing research with hard to understand words with my schoolwork. It helps me understand what the text is talking about and now I can have a trusted site at my finger-tips. Great Work all!

Extremely handy extension. Works very well. No problems encountered so far. * TIP: If you have trouble finding definitions for a word and it reports that: [Sorry, we couldn't find any matching definitions...] Try not using plurals. Eg: Use, ie highlight: "allusion" instead of "allusions".
