Note that some of these tags are inappropriate, so just because a tag exists, doesn't mean you should use it. (Some are apparently dates the sentences were added to the database, and other strange ones, too.)
The "Category" column includes some ideas for sorting tags into categories. I just grabbed ideas I had from several years ago. I roughly sorted them at that time. Some tags have been added since then. It's a column you can sort to group tags.
Click a column title to sort that column. Click again to reverse the sort. The default sort is marked in green.
