Words at Play : 8 Spelling Suggestions That Didn't Stick
#8: "Dont" instead of "Don't"
Who Proposed the Change:
George Bernard Shaw
Why the Change:
George Bernard Shaw had no love for superfluous punctuation, and did away with many (but not all) of the apostrophes in several of the printed versions of his plays, reasoning that people would understand what was meant without them.
He began by changing don't to dont and mustn't to mustnt, but Shaw had grander dreams for English orthography, a system he found profoundly deficient. He left money in his will for whoever could come up with an improved system of writing, which would be called Shavian.
