🌈 The Big Picture

• Final consonant (batchim) → $$\color{purple}{\text{을}}$$ [eul]

• Vowel → $$\color{purple}{\text{를}}$$ [reul]

🧩 Core Pattern

• $$\color{purple}{\text{책}}$$ [chaek] + $$\color{purple}{\text{을}}$$ → $$\color{purple}{\text{책을}}$$ [chae-geul]

• $$\color{purple}{\text{물}}$$ [mul] + $$\color{purple}{\text{을}}$$ → $$\color{purple}{\text{물을}}$$ [mu-reul]

• $$\color{purple}{\text{사과}}$$ [sa-gwa] + $$\color{purple}{\text{를}}$$ → $$\color{purple}{\text{사과를}}$$ [sa-gwa-reul]

• $$\color{purple}{\text{커피}}$$ [keo-pi] + $$\color{purple}{\text{를}}$$ → $$\color{purple}{\text{커피를}}$$ [keo-pi-reul]
