As a linguistic expert with a keen interest in etymology, I often delve into the fascinating origins of idioms and phrases. The term "wet behind the ears" is a prime example of the colorful expressions that have been woven into the tapestry of the English language. This phrase is used to describe someone who is very young, inexperienced, or naive.

The origin of "wet behind the ears" is quite literal and vivid. It refers to a newborn animal, particularly a calf or a foal, that has just been born and is so new to the world that its ears are still wet from birth. The image this phrase conjures is one of a creature so fresh from the womb that it has not yet had the chance to dry off completely.

This idiom has been in use in the United States since the early 20th century, as you mentioned, and it predates its first recorded use elsewhere by about two decades. The phrase was particularly prevalent in American English, where it was used to describe young individuals who were new to a particular situation or environment and had not yet gained the necessary experience or maturity.

Interestingly, the phrase has a converse, "dry back of the ears," which was also known in the United States around the same time. This expression is less commonly used today but it carries a similar meaning, suggesting that someone has gained experience and is no longer as naive or inexperienced as they once were.

The use of such vivid imagery in language is not uncommon. Idioms often rely on metaphorical or figurative language to convey a particular meaning. In this case, the phrase "wet behind the ears" uses a literal image to create a metaphor for inexperience. It's a testament to the power of language to evoke strong visual and emotional responses.

Over time, phrases like "wet behind the ears" become ingrained in the language and are passed down through generations. They serve as a reminder of the cultural and historical context from which they emerged, and they continue to enrich our communication with their unique and evocative imagery.

In summary, "wet behind the ears" is a phrase that has its roots in the literal description of a newborn animal and has evolved into a metaphor for inexperience. Its early use in American English and the existence of its converse, "dry back of the ears," provide insight into the development and evolution of idiomatic expressions in language.
