‘叫醒’ is a transitive verb meaning 'to wake (someone) up'—it always requires an object (the person being woken). Literally, 叫 means 'to call' or 'to tell', and 醒 means 'to wake up' or 'to become awake'. Together, they form a compound verb expressing the action of causing someone to stop sleeping, typically by calling their name, shaking them, or using an alarm. It’s commonly used in daily routines, especially when describing morning routines, caregiving, or scheduling.

This word emphasizes intentionality: the subject actively intervenes to rouse another person. It’s neutral in register—appropriate in both casual speech and formal contexts—and is rarely used reflexively (e.g., you wouldn’t say *我叫醒* to mean 'I woke up'; use 醒来 instead). It often appears with time phrases (e.g., 七点叫我醒) or agents (e.g., 妈妈叫我醒).
