This is the only sense of 'nod' used for deliberate social communication. When transitive, the only natural object is 'head' — you cannot 'nod a person' or 'nod a greeting' directly. Use 'nod at someone' or 'nod to someone' for the person being greeted.

I nodded at him when I saw him.
💡'nod' is usually intransitive when referring to the person; use 'nod at/to + person'.

用法筆記

The phrasal verb 'nod off' is far more common than the bare 'nod' for the meaning 'fall asleep'. Bare 'nod' typically describes only the head-dropping motion, whereas 'nod off' implies the person actually falls asleep briefly. Use the continuous form (was nodding / nodding off) naturally.

常見錯誤

I nodded during the meeting.' (ambiguous — could mean agreement or drowsiness)
I nodded off during the meeting.
💡Use 'nod off' to make the falling-asleep meaning clear.
