Why Is There Confusion over the Plural of Crisis?

"Crises" is the only way to make the noun "crisis" plural. Confusion arises because some mistakenly believe that all nouns ending in "s" should form a plural that adds "es" to the end of the word. When a noun ends with "is," you need to replace the "is" with an "es" to form the plural. This is because its plural form derives from Greek. author logo
