Most of us don’t think twice about plural forms — we just kind of know them. But when you actually have to spell them out, things get trickier. Is it “knifes” or “knives”? “Cactuses” or “cacti”? English doesn’t always play by the rules.
This quiz will test how well you know the plural forms of 25 words — and how well you can type them out. There’s no multiple choice and no hints.
