The Origin of Coarse or Course
Understanding the origin of course or coarse explains why they look and sound alike.
Origin of Course
The word course comes from the Latin cursus, meaning a running or a path. It entered English through Old French and kept the idea of movement, progression, or sequence. Over time, its meaning expanded to include:
- A path or direction
- A series of lessons
- A stage in a meal
Origin of Coarse
Coarse comes from Old French coars or cours, meaning rough or ordinary. Its meaning stayed focused on texture and quality, especially things that are not smooth or refined.
Why the Confusion Exists
Both words evolved from similar French roots and became homophones in English. While pronunciation stayed the same, spelling and meaning split into two clear paths one abstract (course) and one descriptive (coarse).
