scab (SKAHB) (s) (noun), scabs (pl)
1. A "crust over a wound" that forms on a surface of missing skin from an injury which is composed of dried blood that forms over a cut or broken epidermis while it is healing: Sally stumbled and fell on the sidewalk which caused damage to her knees and resulted in scabs being on them while she was recuperating.

Little Jimmy was told that he should not pick at his scabs or try to remove them with his fingers because he would make the healing of his knees take much longer or even cause more pain.

2. Etymology: comes from Old English scaeb, "the crust that forms on a sore" which apparently is related to Latin scabies, "scab, itch, mange"; from scabere, "to scratch".
