Meaning and origin of William

William is a Germanic and English name that means “resolute protector”.

William comes from the Germanic elements wil, "will" or "desire", and helm, "helmet" or "protection", and is often rendered "resolute protector". William the Conqueror brought it to England with the Norman Conquest of 1066, and it quickly became one of the most common English names. Four kings of England and Britain have borne it, and it remains prominent in the British royal family. William Shakespeare and William Wordsworth are among its famous literary bearers. The name feels dependable and timeless, and it offers an unusually wide range of nicknames: Will, Billy, Bill and Liam. Liam in particular has grown into a major independent name.
