What is the plural form of 'millennial'?
Millennial is an adjective and doesn't have a plural. The noun it is based upon is millennium. The word millennium can be made plural in two ways that are equally acceptable. You can use millennia, which follows the Latin rule for plural, or you can use millenniums, which is the standard English form of plural. For fun, you can think of millennia as being a bit more academic or highbrow, and millenniums as being more hip. If you use millenniums and someone tells you it is an error, you can reply with "Yes, yes, I know the Latin. We are speaking English here..."
