On leaving, marks time? (5)
I believe the answer is:
hours
This clue might be a double definition.
'on leaving marks' is the first definition.
The definition and answer can be both human attributes as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'time?' is the second definition.
(I know this)
Can you help me to learn more?
(Other definitions for hours that I've seen before include "A long time" , "Periods of time" , "Matins and Vespers, say?" , "time appointed for work" .)
