In my linguistics class this past spring we discussed the disappearing apostrophe. Based on its lack of proper implementation in projected songs at church, announcements, and billboards, as well as in multiple iterations of student papers, I posited an official termination of the apostrophe to show possession within fifty years. Perhaps, had English a college (governing board which decides what is correct) like many other languages do, it would disappear sooner.
Based on the number of missing possessive markers in the last two paper sets I have graded in all my freshman and sophomore papers, the fifty years may have been too generous of a timeline.
Even after direction from me on where to go to learn about possessives (but not actual instruction as I forgot I had planned it), students failed to wield apostrophes or only threw them helter-skelter into their papers wherever an -s ending appeared.
