Predict he’s taking on Yard after getting support (8)
I believe the answer is:
prophesy
'predict' is the definition.
(I've seen this before)
'he's taking on yard after getting support' is the wordplay.
'taking on' is a charade indicator (letters next to each other).
'yard' becomes 'y'.
'after getting' means one lot of letters go next to another.
'support' becomes 'prop' (prop is a kind of support**).
'hes' put next to 'y' is 'hesy'.
'hesy' put after 'prop' is 'PROPHESY'.
(Other definitions for prophesy that I've seen before include "Say that something will happen in the future" , "Reveal through divine inspiration" , "Prediction" , "Predict" , "Foretell - portend" .)
