Suppose that we're playing a card game. One of the rules is that you can double the numerical value of a card if it fulfills a set of conditions.
So, there are two types of cards: those that can be doubled and those that can't.
Is there a single word that can be used to describe a card that "can be doubled"? Basically, double-able.
None of your cards is double-able!
Which sounds a bit awkward. I know that I can say
None of your cards can be doubled!
But I was wondering if there is a one-word solution.
