Agreed, leaving, and lost consciousness (6,3)
I believe the answer is:
nodded off
'lost consciousness' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'agreed leaving' is the wordplay.
'agreed' becomes 'nodded' (I've seen this in another clue).
'leaving' becomes 'off' ('I'm off' means 'I'm leaving').
'nodded'+'off'='NODDED OFF'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for nodded off that I've seen before include "dozed" , "Fell asleep" .)
