26/4/19 A feather in your cap

This term is an idiom that refers to an achievement to be proud of. The placing of a feather in a hat has been a symbol of achievement that has arisen in several cultures, apparently independently. For example, some cultures had the custom of adding a new feather to their head-gear for every enemy slain. The phrase today has altered to a more peaceful allusion, where it is used to refer to any laudable success or achievement by an individual that may help that person in the future.

Example: 
– Congratulations. This must be quite an honor. 
– Yes, it is quite a feather in my cap.
