Editing Trivium (section)

==Etymology==
Etymologically, the Latin word {{lang|la|trivium}} means "the place where three roads meet" ({{lang|la|tri}} + {{lang|la|via}}); hence, the subjects of the trivium are the foundation for the [[quadrivium]], the upper (or "further") division of the [[Middle Ages|medieval]] education in the [[liberal arts]], which consists of [[arithmetic]] (numbers as abstract concepts), [[geometry]] (numbers in space), [[music]] (numbers in time), and [[astronomy]] (numbers in space and time). Educationally, the trivium and the quadrivium imparted to the student the seven liberal arts of [[classical antiquity]].<ref name="english-ety" />
