Etymology of William
William derives from the Germanic elements wil (will, desire) and helm (helmet, protection), traditionally interpreted as meaning "resolute protector" or "strong-willed warrior". The name entered English through the Norman Conquest of 1066, when William the Conqueror became King of England.
The original Germanic form was Willahelm, which evolved into Wilhelm in German and Guillaume in French. The Normans brought the French form to England, where it quickly transformed into the anglicized "William" we recognize today.
The name's martial meaning reflects the warrior culture of medieval Europe, where protection and willpower were highly valued traits for nobility and leadership.
