Angry will not be put in the same category as “apple”. Starting with the same letter is not enough to qualify a word for the same category. The qualification must be based on a variety of factors including the part of speech and the composition of the word as noted in Joe's argument. However, whether a word fits in a category will not be decided by a mechanical scoring process where pros must outnumber cons. The number of pros and cons can be persuasive though.
The next word is “Sharp”. Should "sharp" be in the same category as "apple"?
