Sun's to rise with a hint of light being introduced (5)
I believe the answer is:
solar
'sun's' is the definition.
(I know this)
'rise with a hint of light being introduced' is the wordplay.
'rise with' becomes 'soar' (soar is a kind of rise. I am not sure about the 'with' bit.).
'a hint of' suggests taking the first letters (the smallest possible amount of the word).
'being introduced' indicates putting letters inside (some letters are introduced or inserted in).
The first letter of 'light' is 'l'.
'soar' placed around 'l' is 'SOLAR'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for solar that I've seen before include "Of or derived from the sun" , "Of the sun, as ray or panel" , "room" , "Using the energy of the sun" , "sunny?" .)
