Etymology

From Middle English William, from Anglo-Norman Willame, from Old High German Willahelm, from Proto-Germanic *Wiljahelmaz (> Latin Gulielmus), from Proto-Germanic *wiljô (“will”) + *helmaz (“helmet”), ultimately from the Proto-Indo-European roots *welh₁- (“to choose, wish, want”) and *ḱel- (“to cover, conceal, save”) respectively. Cognate with Dutch Willem, German Wilhelm, etc.; cognate borrowings outside of Germanic include Guillaume and Guillermo.
