Notes
GENERAL INFO
Cours is a masculine noun meaning 'class', 'lesson' (academic), 'flow' (of water/river), or 'price' (e.g., market price). It is also the present tense conjugation of the verb 'courir' (to run) for 'tu', 'il', 'elle', 'on'.
USAGE
As a noun: "J'ai un `cours` de maths." (I have a math class). "Le `cours` de la rivière." (The flow of the river). As a verb: "Tu `cours` vite." (You run fast).
TRAPS
The main trap is confusing the masculine noun `un cours` (class, flow) with the verb `cours` (you/he/she runs). Context and preceding words (like articles or pronouns) are crucial for distinguishing them.
