A mugger is someone who attacks a person in a public place — a street, a park, a station — and takes money, a phone, or a bag. It is usually quick and close, not a planned break-in at a house. The verb is to mug; the person who does it is the mugger. News English uses it in a plain, serious way. Though actually, mug in older British slang also means “face” and “fool”, and there is a completely different animal also called a mugger (a kind of crocodile in South Asia). That animal is another word with the same spelling, not this robber. This entry is only the street attacker.
