Morphology

nod + off

Given the provided sense of 'nod' as 'to start dozing' and 'off' as indicating movement away or a change of state, the combined meaning 'to fall asleep briefly' is directly compositional and predictable. This motion/change-of-state pattern with a verb + particle is common and readily inferable by a B1 learner who knows both constituents.

Etymology

The phrase nod off may come from the slow head movement when you begin to sleep: your head makes a small nod and then seems to drop off. That's why it means 'to fall asleep for a short time, usually without meaning to'.
