Donel, pronounced /doʊˈnɛl/ in English, is a unisex appellation of Gaelic origin, tracing its lineage to the Old Irish name Domnall and formed from the elements domhan (“world”) and val (“mighty”), thereby etymologically denoting “ruler of the world.” Throughout the mid-twentieth century in the United States, it appears intermittently in national birth registers, attaining modest peaks—five instances (rank 724) in 1954 and seven instances (rank 744) in both 1968 and 1974—thus illustrating its rare but persistent adoption within Anglo-American naming conventions. The name’s phonological transparency and morphological fidelity to its Celtic roots endow it with a reserved yet authoritative resonance, meeting contemporary onomastic preferences for gender-neutral designations while preserving its historical gravitas.
