Pliny thought that the name "Druid" was a Greek appellation derived from the Druidic cult of the oak ([Greek: _drus_]).[1002] The word, however, is purely Celtic, and its meaning probably implies that, like the sorcerer and medicine-man everywhere, the Druid was regarded as "the knowing one." It is composed of two parts--_dru_-, regarded by M. D'Arbois as an intensive, and _vids_, from _vid_, "to know," or "see."[1003] Hence the Druid was "the very knowing or wise one." It is possible, however, that _dru_- is connected with the root which gives the word "oak" in Celtic speech--Gaulish _deruo_, Irish _dair_, Welsh _derw_--and that the oak, occupying a place in the cult, was thus brought into relation with the name of the priesthood. The Gaulish form of the name was probably _druis_, the Old Irish was _drai_. The modern forms in Irish and Scots Gaelic, _drui_ and _draoi_ mean "sorcerer."
