The Meaning Behind the Idiom

“Wet behind the ears” is an expression used to describe someone who lacks experience or knowledge in a particular area. It suggests that they are still new or inexperienced and have yet to gain enough wisdom or expertise.

The Origins of the Idiom

The origin of this idiom dates back several centuries when horses were commonly used for transportation. When foals were born, their coats would be damp with amniotic fluid from birth, making them appear wet behind their ears.

As these foals grew up and gained more experience running around fields and pastures, their coats would dry out completely. This led people to use the phrase “wet behind the ears” as a way of describing someone who was inexperienced or naive about something.
