The name Werner has its origins in the Germanic languages, specifically Old High German. It is derived from the root words "warin", meaning "to guard" or "to protect", and "hari", meaning "army" or "warrior". The combination of these two words gave rise to the name, which can be interpreted as "guardian warrior" or "protector of the army".

The name Werner can be traced back to the 8th century and was commonly used among the Frankish and Alemannic tribes that inhabited present-day Germany, France, and Switzerland. It gained popularity during the Middle Ages, particularly among the nobility and military class, as it embodied the ideals of strength, courage, and loyalty.

One of the earliest recorded instances of the name Werner can be found in the Hildebrandslied, an Old High German heroic poem dated around the 9th century. The poem features a character named Werner, who is depicted as a brave and valiant warrior.
