How it's used
Used primarily in scientific or formal contexts like 沸點 to describe the physical state of boiling. In everyday spoken Cantonese, people almost exclusively use 滾 to describe water that has reached its boiling point. You will rarely hear a native speaker use 沸 as a standalone verb in casual conversation.
