I think the dictionary is a good idea if one knows what they want to learn about. But, a word a day feature would be an interesting teaching tool.
Also wanted to ask if there is a pronunciation guide on this site? Fine Gardening magazine has an excellent one with an audible option. If we don't already hove on someplace could we link to Fine Gardening's? Maybe it could be added to the Dictionary or the word a day.
