Since I know there’s at least a couple English teachers out there, I figure this is a good place to answer my question.
In this article, I have the following quote:
GM plans to produce 10,000 Volts next year, and 30,000 in 2012, company officials have said. Nissan has indicated that it will sell about 25,000 Leafs in the United States next year.
Since Leaf is being used as a proper noun, does it not follow the normal pluralization and become “Leaves”?
As far as I know, “Leafs” isn’t a word — or wasn’t until it became a proper noun when Nissan chose it for a car.
What’s the rule here?
