Inducement of vehicle? Nonsense (6)
I believe the answer is:
carrot
'inducement' is the definition.
(I've seen this before)
'vehicle? nonsense' is the wordplay.
'vehicle?' becomes 'car' (car is a kind of vehicle).
'nonsense' becomes 'rot' (rot can mean nonsense or rubbish).
'car'+'rot'='CARROT'
'of' acts as a link.
(Other definitions for carrot that I've seen before include "The vegetable for persuasion" , "The vegetable to induce" , "Enticement; vegetable" , "Orange vegetable" , "veg" .)
