Where does teacher come from?
The word entered English from Old French teachier, which was based on Latin docere, “to teach.” The same Latin root produced related English words such as docent, docile, doctor, and document, all connected with teaching, learning, or instruction. Teacher developed in English as the name for a person who performs the activity of teaching, later extending beyond the classroom to other forms of instruction.
