"skin disease of hairy animals," especially dogs, often caused by mites, c. 1400, manjeue, maniewe, from Old French manjue, mangeue "the itch," also "hunger, appetite; itching, longing," literally "the eating," verbal noun from a collateral form of Old French mangier "to eat" (Modern French manger) "to eat," from Late Latin manducare "to chew, eat," from manducus "glutton," from Latin mandere "to chew" (see mandible).
"chronic non-contagious skin disease characterized by dry, red patches covered with flakes," 1680s, from medical Latin psoriasis, in Late Latin "mange, scurvy," from Greek psōriasis "the itch; a being itchy," from psōrian "to have the itch," from psōra "itch, mange, scab," related to psēn "to rub" (see psilo-). Related: Psoriatic.
skin disease characterized by eruptions and inflammation, c. 1400, "the itch; scabby skin generally," from Latin scabies "mange, itch, roughness," from scabere "to scratch, scrape" (from PIE root *(s)kep-, a base forming words meaning "to cut, scrape, hack," source also of Gothic scaban, Old English sceafan "to scrape, shave;" Greek skaptein "to dig;" Old Church Slavonic skobli "scraper;" Lithuanian skabus "sharp," skabėti "to cut;" Lettish skabrs "splintery, sharp").
Modern medical use in reference to a contagious skin disease due to a parasitic mite is by 1814. The older name for a skin condition or disease was simply scab. Scabbed "afflicted with scabies or mange" is by c. 1300. Related: Scabious.
machine for smoothing and pressing linen and cotton clothes after washing, 1774, from Dutch mangel (18c.), apparently short for mangelstok, from stem of mangelen to mangle, from Middle Dutch mange, which probably is somehow from to Vulgar Latin *manganum "machine" (see mangonel), "but its history has not been precisely traced" [OED].
The possession of a mangle, for the use of which a small sum was charged, is, among the poorer classes of English cottagers, a common means of earning money. The question 'Has your mother sold her mangle?' (quot. 1836-7) was at one time the commonest piece of 'chaff' used by London street-boys. [OED]
"box or trough in a stable or cow-shed from which horses and cattle eat food other than hay" (which generally is placed in a rack above the manger), early 14c., maunger, from Old French mangeoire "crib, manger," from mangier "to eat" (Modern French manger) "to eat," from Late Latin manducare "to chew, eat," from manducus "glutton," from Latin mandere "to chew" (see mandible). With Old French -oire, common suffix for implements and receptacles. In Middle English, to have at rack and manger was an image for "keep (a mistress, followers, etc.), supply with life's necessities."
mid-13c., in a general sense, "skin disease, 'the itch,' " developed from Old English sceabb (related to scafan "to shave, scrape, scratch") and from its cognate, Old Norse skabb, both from Proto-Germanic *skab- "scratch, shave" (from PIE *(s)kep- "to cut, scrape, hack;" see scabies). Likely reinforced by resemblance of the plural to Latin cognate scabies "scab, itch, mange" (from scabere "to scratch").
The word was extended late 14c. to the patches or ulcerations accompanying the disease, hence the main modern meaning "crust which forms over a wound or sore," attested by c. 1400.
The colloquial meaning "strikebreaker" is recorded by 1806, from earlier colloquial sense of "person who refuses to join a trade union" (1777), probably from meaning "despicable person; mean, paltry fellow" (1580s), which, according to OED, is possibly from Dutch, where a similar sense had developed. The flood-scoured scablands of the Pacific Northwest were so called by 1923.
