jack

If you're ever stranded beside the highway with a flat tire, what you need is a jack and a spare tire. With a jack, you can lift the car slightly off the ground and change the tire.

Most cars have an emergency jack in the trunk, and repair shops have larger jacks, sometimes called "garage jacks," that can raise the car high enough for a mechanic to work underneath it. To lift this way is to jack something. Other kinds of jacks include game pieces and playing cards. In Middle English, as now, the name Jack was used for "ordinary guy," a meaning that transferred to basic tools, generic men, and male animals.
