Bill about to enter woodland that's divine (8)
I believe the answer is:
forecast
'divine' is the definition.
(I've seen this before)
'bill about to enter woodland' is the wordplay.
'bill' becomes 'ac'.
'about' is a reversal indicator.
'to enter' indicates putting letters inside.
'woodland' becomes 'forest' ('forest' can be a synonym of 'woodland').
'ac' back-to-front is 'ca'.
'ca' placed inside 'forest' is 'FORECAST'.
'that's' is the link.
(Other definitions for forecast that I've seen before include "Prediction, about the weather perhaps" , "Tell in advance what will happen" , "Fear Scot in prediction" , "Meteorological surmise perhaps" , "Expect" .)
