Took the rest of the night (5)
I believe the answer is:
slept
'took' is the definition.
The definition and answer can be both related to bodily activities as well as being past participle verbs.
Perhaps you can see an association between them that I can't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for slept that I've seen before include "Had room for" , "appeared still" , "Was dormant" , "Napped, dozed" , "Slumbered" .)
