Which is Correct: Growns-Up or Grown-Ups?

As children, we all yearned for the freedom and independence of being a grown-up. But when it comes to using the word "grown-up" in its plural form, people often get confused. Is it "grown-ups" or "growns-up"? In this blog post, we'll explore the plural of "grown-up" and provide some examples to help clarify.

Now, let's address the plural form of "grown-up." The correct plural is "grown-ups." This is because "grown-up" is a compound noun made up of two words, "grown" and "up." 

When forming the plural of a compound noun which is not made of nouns itself, we usually add an "s" to the end of the word. In this case since neither “grown” nor “up” is a noun, the plural of “grown-up” is “grown-ups.”

This follows the same rule as words such as check-in, “sit-up”, and “good-for-nothing”, and all other compound nouns which are made from other word types such as verbs, adjectives, and prepositions.
