Prediction concerning Eastern actors (8)
I believe the answer is:
forecast
'prediction' is the definition.
(I know that forecast is a type of prediction)
'eastern actors' is the wordplay.
I cannot really see how this works, but
'eastern' could be 'e' and 'e' is found within the answer.
an anagram of 'actors' is 'orcast' which is present in the remaining letters.
A single letter 'f' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'concerning' is the link.
Can you help me to learn more?
(Other definitions for forecast that I've seen before include "Prediction, about the weather perhaps" , "tip" , "Divine" , "Predict as with weather" , "Expect" .)
