Homonym: Scab (Worker)
A "scab" is a protective crust that forms over a wound as it heals. This natural process occurs when the body produces a clot of blood and cells to cover the injury, preventing infection and further damage. Scabs are typically brown or dark red and can vary in size depending on the severity of the wound.
In a different context, the term "scab" can refer to a person who works in place of striking workers during a labor dispute. This usage is often seen in discussions about labor rights and unions, where labor unions advocate for fair working conditions and wages.
