The present Dawn has to give Dan (3)
I believe the answer is:
now
'the present' is the definition.
(both can mean the current period)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for now that I've seen before include "At the present time" , "At this moment in time" , "At present, this instant" , "The present moment" , "straight away" .)
