English Idioms: Age Related Idioms Explained Simply

Age-related idioms are common English expressions that talk about different stages of life—childhood, youth, adulthood, and old age. Native speakers use these idioms in daily conversations, stories, and even movies.

For English learners, these idioms can be confusing because their meanings are not literal. For example, when someone says “over the hill,” it does not mean climbing a hill—it means someone is getting old.

In this lesson, we will explore age-related English idioms explained in very simple language, so learners can understand them easily and use them confidently in real-life conversations.

Have you ever heard someone say, “You can’t teach an old dog a new trick” or refer to a young person as a “spring chicken?”

Idioms like these that relate to age are used all the time in the English language.

An idiom is a phrase that has a figurative meaning different from the literal meanings of the individual words.

Today, we’re going to take a look at 25 common idioms about age and explain what they mean.

Some relate to being young, others to being old, and many compare age differences.

Understanding these idioms will help expand your English vocabulary in a fun and interesting way.
