"building for storage," 1855, earlier "light, temporary shelter" (late 15c., shadde), possibly a dialectal variant of a specialized use of shade (n.). Originally of the barest sort of shelter. Or from or influenced in sense development by Middle English schudde (shud) "a shed, hut."
shed (v.) Look up shed at Dictionary.com
"cast off," Old English sceadan, scadan "to divide, separate, part company; discriminate, decide; scatter abroad, cast about," strong verb (past tense scead, past participle sceadan), from Proto-Germanic *skaithan (cognates: Old Saxon skethan, Old Frisian sketha, Middle Dutch sceiden, Dutch scheiden, Old High German sceidan, German scheiden "part, separate, distinguish," Gothic skaidan "separate"), from *skaith "divide, split."

According to Klein's sources, this probably is related to PIE root *skei- "to cut, separate, divide, part, split" (cognates: Sanskrit chid-, Greek skhizein, Latin scindere "to split;" Lithuanian skedzu "I make thin, separate, divide;" Old Irish scian "knife;" Welsh chwydu "to break open"). Related: Shedding. A shedding-tooth (1799) was a milk-tooth or baby-tooth.

In reference to animals, "to lose hair, feathers, etc." recorded from c.1500; of trees losing leaves from 1590s; of clothes, 1858. This verb was used in Old English to gloss Late Latin words in the sense "to discriminate, to decide" that literally mean "to divide, separate" (compare discern). Hence also scead (n.) "separation, distinction; discretion, understanding, reason;" sceadwisnes "discrimination, discretion."

1846, from Irish Sile na gcioch, literally "Sheila of the breasts" [OED]. According to modern folklorists, not a Celtic survival, but originating rather in the Romanesque churches of France and northern Spain.

sheeney (n.) Look up sheeney at Dictionary.com

sheep (n.) Look up sheep at Dictionary.com
ruminant mammal, Old English sceap, scep, from West Germanic *skæpan (cognates: Old Saxon scap, Old Frisian skep, Middle Low German schap, Middle Dutch scaep, Dutch schaap, Old High German scaf, German Schaf), of unknown origin. Not found in Scandinavian (Danish has faar for "sheep") or Gothic (which uses lamb), and with no known cognates outside Germanic. The more usual Indo-European word for the animal is represented in English by ewe.

The plural form was leveled with the singular in Old English, but Old Northumbrian had a plural scipo. Used since Old English as a type of timidity and figuratively of those under the guidance of God. The meaning "stupid, timid person" is attested from 1540s. The image of the wolf in sheep's clothing was in Old English (from Matt. vii:15); that of separating the sheep from the goats is from Matt. xxv:33. To count sheep in a bid to induce sleep is recorded from 1854 but seems not to have been commonly written about until 1870s. It might simply be a type of a tedious activity, but an account of shepherd life from Australia from 1849 ["Sidney's Emigrant's Journal"] describes the night-shepherd ("hut-keeper") taking a count of the sheep regularly at the end of his shift to protect against being answerable for any animals later lost or killed.

Sheep's eyes "loving looks" is attested from 1520s (compare West Frisian skiepseach, Dutch schaapsoog, German Schafsauge). A sheep-biter was "a dog that worries sheep" (1540s); "a mutton-monger" (1590s); and "a whore-monger" (1610s, i.e. one who "chases mutton"); hence Shakespeare's sheep-biting "thieving, sneaky."
