missing apostrophes

Not missing - part of puzzle wazzack!

In my copy of the canterbury tales, they all have apostrophes - as they should, because they are all singular and the "s" indicates possession. Who is the wazzock now?

@Nighteyes, the first use of the apostrophe was by Pietro Bembo in De Aetna in 1496. Chaucer wrote his Canterbury Tales between 1387-1400. Therefore there were NO apostrophes in his original manuscript which you would have known if you had the first edition. I used one apostrophe to make the grid unique and as a puzzler, I assumed you and Bob would recognise, PS you misspelled my wazzack.
