A tireless slug that turns tiny explosions into your morning commute, thousands of times a minute.
means A solid cylindrical part that slides up and down inside an engine's tube, transferring the force of expanding gases (or pressure) into motion.
from From French 'piston,' itself borrowed from Italian 'pistone,' a beefed-up form of 'pistare,' meaning to pound or crush. Trace it further back and you reach Latin 'pinsere,' to stamp or grind — the same root that underlies 'pestle,' that little tool you mash garlic with. So a piston is, etymologically, a pounder, which is exactly what it does down in the cylinder.
