Golf shot somewhat missed a fairway going backwards (4)
I believe the answer is:
fade
'golf shot' is the definition.
(I know that fade is a type of golf shot)
'somewhat missed a fairway going backwards' is the wordplay.
'somewhat' indicates a hidden word.
'going backwards' says the letters should be written in reverse.
'edaf' is hidden within 'missed a fairway'.
'edaf' backwards is 'FADE'.
(Other definitions for fade that I've seen before include "Gradually grow faint" , "Grow dull" , "Grow dimmer" , "Diminish" , "Lose brightness" .)
