That which may make us brown paper? (3)
I believe the answer is:
sun
'paper?' is the definition.
(The Sun, UK newspaper)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sun that I've seen before include "Helios, in Greek myth" , "Star that provides light and heat for a solar system" , "Hub of our planetary system" , "Nearest star to Earth" , "Our central star" .)
