Just Learned Something about Until, Till and 'Til
Sometimes I have a bunch of authors making the same error, and that's a clue to me to verify, verify, verify ... as I might be making a mistake, too, by fixing something that's evolved into being correct, or at least informal, usage in the decades since I started in this business. That was the case with till and 'til. Writers have been using till quite a lot lately in the documents they send me for editing.
I grew up being taught that, among its many meanings, till was what you did to soil when you prepared it for seed-planting time or it was the place where you put money, and until became 'til in informal usage.
So many authors were using till that I decided to have a look-see, and here's what I found at World Wide Words, by Michael Quinion, who writes on International English from a British viewpoint: http://www.worldwidewords.org/qa/qa-unt1.htm
