Etymology

It is from doceō “to teach” with the agent suffix -tor.[2][1][3] Doceō goes back to Proto-Indo-European *deḱ- (“to take, accept”).[1]

Earliest recorded meaning

Semantic evolution

It meant a teacher, instructor or trainer, as in Cicero, Horace and Quintilian.[2][5] In the Vulgate it was a teacher of the law.[5] Döderlein says doctor is a teacher who imparts theory to a student, praeceptor one who leads a pupil to practice.[6]

In Christian and Medieval Latin it meant an apostle, a Father of the Church, and a religious teacher or scholar.[7][3] It survives in Italian dottore and Portuguese doutor.[1] English doctor came about 1300 through Old French doctour, first meaning a Church father.[3]
