The plural of grown-up is grown-ups.
Grown-up is an adjective that describes a person who is fully developed or mature, especially in terms of behavior or attitudes. It can also be used as a noun to refer to an adult. It is a common term used in everyday conversation and literature.
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.
To illustrate, here are three example sentences each with the singular and plural noun forms of "grown-up":
