like water off a duck’s back: Idiom Meaning and Origin

The idiom "like water off a duck's back" is a phrase used to describe a situation or event that has little or no effect on someone. It suggests that negative comments or criticism directed towards a person or situation are easily disregarded or ignored. This idiom is often used to express resilience or the ability to remain unaffected by negative or critical remarks.

The origins of this idiom can be traced back to the behavior of ducks and their unique waterproof feathers. Ducks have a gland near the base of their tails that produces an oily substance called preen oil. They spread this oil across their feathers using their beaks, which makes their plumage tightly knit and waterproof. When water comes into contact with the duck's feathers, it forms into droplets and slides off easily, leaving the duck dry and unaffected by the water.

The metaphorical use of this idiom emerged in the English language during the early 19th century. It is believed to have originated from the observation of the physical behavior of ducks and their ability to repel water. The phrase gained popularity due to its vivid imagery and relatable concept, resonating with people facing criticism or adversity in various situations.
