I've been known to hit up a Dunkin Donuts occasionally. And I can't resist any opportunity to go to Duck Donuts. But you will never catch me eating a donut, and neither should you.
Traditionally, a donut is a type of metal gasket.
Through the years, however, this spelling has been used in reference to those magical dried dough treats being honored today. According to Merriam Webster, the variant donut has been used "in published, edited text since the mid-20th century." Many dictionaries accept it. Yet the Associated Press and I still uses doughnut.
What are your thoughts?
