William — Name Meaning, Origin & Popularity

William is a boys' name of Germanic origin, meaning "resolute protector". A thousand years of kings, Shakespeares, and Williams — the conqueror's name.

Style & feel. With classic and royal on its style card, William sits comfortably in the modern naming landscape — familiar enough that nobody misreads it, distinctive enough that your child won't share it with three classmates. At 2 syllables, it flows across most middle-name combinations and survives every life stage from playground to résumé.

Pairing ideas. William pairs naturally with one- and two-syllable middles (Henry, James share its sound-world). If you like William, you'll probably also love Henry, James, Theodore — same era, same energy, same bone structure.
