What does robber mean? A robber is a person who robs—steals, especially by force or through threats of violence. In other words, a robber is someone who commits robbery. A robber can rob a person or a place, such as a house or business. A robber who robs a person on the street is often called a mugger. A person who robs a bank is called a bank robber and the act of doing this is called bank robbery. An armed robber is a person who commits armed robbery, which involves robbing a person or place while armed with a weapon. A robber is a kind of thief, which is a person who steals things. However, the word thief usually refers to a person who steals without anyone noticing, at least not when the theft is taking place. In contrast, a person who steals by using force, violence, or threats of force or violence would more likely be called a robber. The word rob can also be used in a kind of figurative way meaning to unfairly deprive someone of something, but robber is only used to refer to someone who robs in the literal sense. Example: Police have released sketches of the suspects in the hopes that someone can identify the bank robbers.

Explanation
A robber is someone who steals from another person. A bank robber might steal money from a teller by claiming to have a gun, while a robber baron is much more subtle. Robbery is the crime that robbers commit, taking someone's property or money by hurting them or threatening to hurt them. You might picture train robbers in an old Western movie, galloping away with their loot shooting their guns in the air. In the nineteenth century, Americans began using the term "robber baron" to mean wealthy, unscrupulous businessmen.
