The Academy was formed to spur research

a railway line connected to a trunk line

a sharp prod fixed to a rider's heel and used to urge a horse onward

cowboys know not to squat with their spurs on

a verbalization that encourages you to attempt something

the ceaseless prodding got on his nerves

tubular extension at the base of the corolla in some flowers

any sharply pointed projection
