The word 'curriculum' entered English in the 1630s directly from Latin, where it meant 'a running,' 'a course,' 'a racecourse,' or (by extension) 'a chariot.' It is the neuter form of 'curriculus,' a diminutive of 'currus' (chariot), itself from the verb 'currere' (to run). The application of a racing metaphor to education — students running through a prescribed course of studies — was apparently first made at the University of Glasgow, whose records from 1633 contain the earliest known use of 'curriculum' in its academic sense.
Latin 'currere' derives from Proto-Indo-European *ḱers- (to run), a root with a notable distribution across the family. In Latin, it produced an extensive word family: 'cursus' (a running, a course — whence English 'course,' 'cursor,' and 'cursory'), 'currēns' (running — whence 'current' and 'currency,' originally 'that which runs' or 'circulates'), 'concurrere' (to run together — whence 'concur'), 'occurrere' (to run toward — whence 'occur'), 'excurrere' (to run out — whence 'excursion'), and 'recurrere' (to run back — whence 'recur'). Through the Germanic branch, the same PIE root *ḱers- is thought to have produced Proto-Germanic *hrussą (horse), giving Old English 'hors' and modern English 'horse' — the animal defined by its running. German preserves a related form in 'Ross' (horse
The connection between 'curriculum' and 'horse' is thus not a coincidence but a genuine etymological relationship: both words spring from the Proto-Indo-European concept of running. A curriculum is a course to be run; a horse is the animal that runs it.
In its original Latin context, 'curriculum' denoted the physical track in a circus or hippodrome around which chariots raced. By extension, it could mean any course or career — Cicero used 'curriculum vitae' (the course of life) in a passage that eventually gave English the phrase 'curriculum vitae' (CV), still used for a summary of one's life and career, particularly in academic and European professional contexts.
The University of Glasgow's 1633 adoption of 'curriculum' to mean the prescribed sequence of academic courses reflects a broader trend in early modern European education. As universities formalized their degree structures, they needed language to describe the organized totality of what a student was expected to study. Latin, the language of academic discourse, supplied the metaphor: the 'course' one runs from matriculation to graduation.
The plural of 'curriculum' follows Latin convention as 'curricula,' though 'curriculums' is increasingly common in informal English. The adjective 'curricular' and its compounds — 'extracurricular' (outside the curriculum), 'co-curricular' (alongside the curriculum) — date from the nineteenth century.
In contemporary educational discourse, 'curriculum' encompasses not just the list of subjects taught but the entire planned learning experience: content, pedagogy, assessment, and sequence. Curriculum theory emerged as a formal field of educational scholarship in the early twentieth century, with figures like John Dewey and Ralph Tyler shaping the debate over what should be taught, how, and why.
The metaphor embedded in the word persists. To 'complete a curriculum' is to finish a course — to cross the finish line of a race that began at enrollment. The word preserves, in its etymology, the ancient Roman image of the chariot careening around the circus track: education as a demanding, structured, goal-directed run toward a finish that confers honor on those who complete it.
