Definition of the word changer

The word "changer" has its roots in Old French "changer", which is derived from the Latin "mutare", meaning "to change". This Latin word is also the source of the English word "change". The meaning of "changer" as a noun, referring to a person or thing that changes something, emerges in the 14th century. In Middle English, the term was used to describe a money changer, someone who exchanges one currency for another. Over time, the term's meaning expanded to include anyone who alters or transforms something, such as a tool, device, or even one's plans. Today, the word "changer" is often used in various contexts, from business (e.g., "He's a key changer in our company's strategy") to personal development (e.g., "She's a life changer, helping people overcome addiction").
