Word Origin & History

scab
mid-13c., "skin disease," developed from O.E. sceabb "scab, itch" (related to scafan "to scratch") and from O.N. skabb "scab, itch," both from P.Gmc. *skab- "scratch, shave" (related to shabby). Sense reinforced by cognate L. scabies "scab, itch, mange" (from scabere "to scratch;" see
scabies). Meaning "crust which forms over a wound or sore" is first attested c.1400. Meaning "strikebreaker" first recorded 1806, from earlier sense of "person who refuses to join a trade union" (1777), probably from meaning "despicable person" (1580s), possibly borrowed in this sense from M.Du.
