I'm rather excited to have discovered Latdict Attractions: Huge vocabulary (apparently based on Whitaker's word list, which drew from multiple sources) Both Latin -> English and English -> Latin Clear user interface Search engine recognizes inflected forms (new parser recently added), pops up reasonable suggestions when you have typed part of a word. In additions to definitions, it tries to say the age (time period) in which the word was in use, area, geography, frequency. Actively developed (new version July 1, 2019) Besides the dictionary, the site has a grammar guide. Detractions: Does not show macrons. Definitions are brief. Does not show examples of usage.
