Wiktionary and Wikipedia agree the original meaning of Níall is uncertain — the widely repeated 'champion' gloss is described as a popular modern suggestion rather than a settled meaning, and 'cloud' is offered as an alternative possibility. Wiktionary's fuller entry adds that the champion-adjacent theory ties the name to a root meaning 'to revile,' but the 'passionate' meaning given elsewhere is not supported by anything found here.
