In Latin apprehendre meant to lay hold of a thing in the sense of learning to understand it, the origin of our "apprehend." This became contracted into apprendre and was applied to a young man beginning to learn a trade. The latter term came into circulation among European languages and, through the Operative Masons, gave us our "apprentice," that is, one who is beginning to learn Masonry. An "Entered Apprentice" is one whose name has been entered in the books of the Lodge.
