Words that are similar, in sound, spelling and/or shorthand outlines. But they might be slightly different written in how Anniversary has the outlines finalized. Please pay attention to the way the succeeding sounds are as well as how the outlines are written prior and before. It can be a bit confusing, but if you know the rules (and perhaps a review of the manual might be in order greggshorthand.proboards.com/thread/312/reviewing-redoing-manual ), you will find that it's not confusing at all.
I started this drill because there was a question about the work "ark" being 'a-r-k' (here). So I went through the dictionary and found a few similar words that start with 'a-c' or close to it. I didn't alphabetize it as I just picked out words and then added others.
