Oliver

Often associated with the olive tree; its original meaning is disputed.

Oliver is a masculine name that comes through Old French Olivier. Its deeper origin is disputed. The olive tree is an established association and one proposed explanation; another is that an older Germanic name was reshaped to resemble the word for olive tree. “Olive tree” is therefore a useful association, but not a settled translation of the original name. The name already belongs to the medieval world of the Song of Roland, where Olivier is Roland’s companion. That gives Oliver a literary dimension beyond the plant image. Its full form can feel composed and classical, while the English short forms Oli and Ollie offer a lighter, more familiar register. The choice is not just how a name looks on paper, but whether that shift between full and short form feels natural to you. British English /ˈɒl.ɪ.və/ and German /ˈoː.li.vɐ/ both have three syllables and stress the first. The opening vowel differs: the German O is long. French Olivier is a related form with an additional I before the ending.

Etymology: Oliver comes through Old French Olivier. A connection with Latin oliva, “olive tree”, is one explanation; another proposes an older Germanic name reshaped through that association.
