Why aren’t the Historical Thesaurus categories in alphabetical order?
The order of subcategories is usually intended to reflect a perceived logical order or order of significance – this order can appear somewhat arbitrary on first impression. For example, many sets of subcategories include ‘other types’ or ‘miscellaneous kinds’, which comes at the end of the set. If strictly alphabetized, these would come in the middle of the list, which would look even stranger.
