Tiny duration (6)
I believe the answer is:
minute
This clue might be a double definition.
'tiny' is the first definition.
(minute can mean small)
'duration' is the second definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for minute that I've seen before include "Measure of time" , "not much time" , "Really very small, like a period of time" , "Sixty seconds" , "Tiny; period of time" .)
