Nail

1. Horny plate covering and protecting part of the dorsal surface of the digits (fingernails). Some ladies like to paint their nails colors, red green and even black.
2. A thin pointed piece of metal that is hammered into materials as a fastener. We use all kinds of nails, box, common and finishing nails, when we work on our home.
3. To keep fixed, motionless. Fear nailed me to my seat.
