There are some spam issues in the comments, so I had to disable comment editing for a short time. It'll be back once the spam bots are gone. FYI... they leave a comment with "great" and then edit in the spam stuff later, to get around the filter.
(This root can be found in most IE languages and it's the origin of a wide range of English words like session, settle, seance, possess, saddle, resident, soil, siege and many more.)
