Just yesterday I saw a post on the shorthand message board on ProBoards about an online Anni dictionary. I found this a rather impressive item, and recommended that the author put up a post here. But because he lives in China, he can’t access Google, and so can’t join this blog. I therefore offered to make the post for him. You can find his dictionary at

Just type in a word and hit the search icon to see the Gregg version. If the word isn’t in the Anni dictionary, this digital dictionary suggests words that are there and that might have similar forms to the desired one.
