Dash put in pastureland (4)
I believe the answer is:
elan
'dash' is the definition.
('elan' can be a synonym of 'dash')
'put in pastureland' is the wordplay.
'put in' says the answer is hidden in the clue.
'ELAN' can be found hidden inside 'pastureland'.
(Other definitions for elan that I've seen before include "French dish in lane" , "Flair and dash" , "Snap" , "Combination of style and vigour" , "Impetuosity - style" .)
