fillip
A little push
A fillip is a snap of the finger—the motion of pressing fingertip against thumb and releasing sharply to strike something.
By extension, a fillip is anything that provides a small stimulus or boost: The tax break gave a fillip to the housing market.
The figurative sense now dominates; the finger-snapping origin is largely forgotten.
