These days, many people use the term “purser” to describe any person or thing that “purrs”. It’s an idiom that describes a person or thing that is constantly doing something or performing something. The words “purr” and “purse” are actually derived from an ancient Sanskrit word, which means “to purr”.
The name purser on a plane is a play on the word for “purse” which is the old English term for a purse. It also means “to make a sound with your mouth”, which is a word that the Puritans used to describe the sound of their religious bells.
