In my book, the forecasters will read something into these (6)
I believe the answer is:
leaves
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for leaves that I've seen before include "Steps out of" , "Organs of photosynthesis" , "takes off" , "They are found on trees and in books" , "spinach for example" .)
