Because pandemics make me peevish.
Listen to me, people. “Dice” is not a singular noun. It is a plural one, as in “a pair of dice” or “cut up your potato into small dice.”
The singular, as any long-time gamer knows, is “die”, as in “roll a twelve-sided die to check for damage.”
One die, two (or more) dice. Get it?
Voice from the back row: Got it.
