"accumulation; ball," 1620s, from Latin glomerationem (nominative glomeratio), noun of action from past-participle stem of glomerare "to wind or form into a ball, roll together, collect," from glomus "ball of yarn, ball-shaped mass," from Proto-Italic *glemos-, from PIE *glem- or *glom-, perhaps originally "ball," but the reconstruction is uncertain (see glebe).
"large miscellaneous collection," by 1830, said to be a variant of raff "heap, large amount," a dialectal survival from Middle English raf (compare raffish, riffraff), with form and sense associated with raft (n.1).

Old English hord "a treasure, valuable stock or store, an accumulation of something for preservation or future use," hence "any mass of things preserved by being deposited together," from Proto-Germanic *huzdam (source also of Old Saxon hord "treasure, hidden or inmost place," Old Norse hodd, German Hort, Gothic huzd "treasure," literally "hidden treasure"), from PIE root *(s)keu- "to cover, conceal."
also oedema, "excessive accumulation of serum in tissue spaces or a body cavity," c. 1400, idema, "a swelling filled with phlegmatic humors," from medical Latin, from Greek oidēma (genitive oidēmatos) "a swelling tumor," from oidein "to swell," from oidos "tumor, swelling," from PIE *oid- "to swell," source also of Latin aemidus "swelling;" Armenian aitumn "a swelling," aytnum "to swell;" Old Norse eista "testicle," Old High German eittar "pus," Old English attor "poison" (that which makes the body swell), and the first element in Oedipus.
late 14c., "a moving, running, or flowing together; a gathering or accumulation," from Old French concours and directly from Latin concursus "a running together," from past participle of concurrere "to run together, assemble hurriedly; clash, fight," from assimilated form of com "together" (see con-) + currere "to run" (from PIE root *kers- "to run").
From early 15c. as "an assembly, a throng." Sense of "open space in a built-up place," especially a gathering place in a railway station, etc., is American English, 1862.

whitish metal element, 1755, the name was coined in 1754 by Swedish mineralogist Axel von Cronstedt (1722-1765) from shortening of Swedish kopparnickel "copper-colored ore" (from which it was first obtained), a half-translation of German Kupfernickel, literally "copper demon," from Kupfer (see copper) + Nickel "demon, goblin, rascal" (a pet form of masc. proper name Nikolaus (compare English Old Nick "the devil;" see Nicholas). According to OED, the ore was so called by miners because it looked like copper but yielded none.
Meaning "coin made partly of nickel" is from 1857, when the U.S. introduced one-cent coins made of nickel to replace the old bulky copper pennies. Application to five-cent piece (originally one part nickel, three parts copper) is from 1883; in earlier circulation there were silver half-dimes. To nickel-and-dime (someone) "make or keep (someone) poor by accumulation of trifling expenses," is by from 1964 (nickels and dimes "very small amounts of money" is attested from 1893).
