"The singular usage is considered incorrect by many authorities. However, it should be noted that The New Oxford Dictionary of English, Judy Pearsall, Patrick Hanks (1998) states that “In modern standard English, the singular die (rather than dice) is uncommon. Dice is used for both the singular and the plural.”
Tell that to every single child's game I have been playing for the last 6 years. I have yet to see "dice" refer to the singular in the instructions (yes, this is something I watch). It is always "throw the die."
D&D as well.
You want me to use the word die for a single dice? No dice! 😄
I guess the die is cast, then.
You guys are on a roll...
