Minor, around one might wake you up (8)
I believe the answer is:
sunlight
'you up' is the definition.
I can't tell whether this definition defines the answer.
'minor around one might wake' is the wordplay.
'minor' becomes 'slight' (I've seen this before).
'around' is an insertion indicator.
'one might wake' becomes 'un' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'slight' placed around 'un' is 'SUNLIGHT'.
Can you help me to learn more?
(Other definitions for sunlight that I've seen before include "Solar illumination" , "Possible reason why blinking" , "Ray" , "Form of illumination" , "Beams" .)
