druid (English)

Where does "druid" come from?

The English word 'druid' was borrowed from French 'druide'[1][3], which comes through Latin 'Druidae' from the Gaulish and Proto-Celtic form '*druwits'[1][2][3]. This ancient Celtic term literally meant either 'oak-knower' or 'firm knower, great sage'[1]. The Proto-Celtic form combines an element derived from Proto-Indo-European meaning either 'tree' or 'solid, firm, hard' with a root meaning 'to see, to have knowledge'[1], which is also the origin of English 'wizard'[1]. The earliest record of the term in Latin appears in the first century B.C. in the writings of Julius Caesar[1].

Open questions

Scholars debate whether the first part of the Proto-Celtic form derives from the word for oak or from a root meaning firm and solid, with the oak connection often considered a folk etymology. [5]
