Illuminates answers that you are filling up in this grid (6)
I believe the answer is:
lights
'illuminates answers that you are filling up in this grid' is the definition.
'lights' can be an answer for 'illuminates' (I've seen this before). I am unsure of the rest of the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for lights that I've seen before include "Illuminators; lungs" , "Understanding" , "Fairy _;" , "Ignites or illumines" , "with something for the cat" .)
