# wet behind the ears

> English word · Adjective

## Definitions
1. Inexperienced; just beginning; immature (especially in judgment).

## Etymology
First use appears c. 1850 in Pennsylvania, a calque of German feucht hinter den Ohren. From the drying of amniotic fluid of a baby after birth, specifically a newborn farm animal, whose ears are the last to dry, partly because it is licked dry by its mother everywhere else. Alternative forms also derive from German.
