scald (v.): c. 1200, "to be very hot; to afflict painfully with hot liquid or steam," from Old North French escalder "to scald, to scorch" (Old French eschalder "heat, boil up, bubble," Modern French échauder), from Late Latin excaldare "bathe in hot water" (source also of Spanish escaldar, Italian scaldare "heat with hot water"), from Latin ex- "off" (see ex-) + calidus "hot" (see calorie). Related: Scalded; scalding. The noun is c. 1600, from the verb.

scale (n.1): "skin plates on fish or snakes," c. 1300, from Old French escale "cup, scale, shell pod, husk" (12c., Modern French écale) "scale, husk," from Frankish *skala or some other Germanic source, from Proto-Germanic *skælo "split, divide" (cognates: Dutch schaal "a scale, husk," Old High German scala "shell," Gothic skalja "tile," Old English scealu "shell, husk"), from PIE root *(s)kel- (1) "to cut, cleave, split" (cognates: Latin culter "knife," scalpere "to cut, scrape;" Old Church Slavonic skolika "mussel, shell," Russian skala "rind, bark," Lithuanian skelti "split," Old English scell "shell," scalu "drinking cup, bowl, scale of a balance").

In reference to humans, as a condition of certain skin diseases, it is attested from c. 1400. As what falls from one's eye when blindness ends (usually figurative), it echoes Acts ix:18 (Latin tanquam squamæ, Greek hosei lepides).
scale (n.2): weighing instrument, early 15c.; earlier "pan of a balance" (late 14c.); earlier still "drinking cup" (c. 1200), from Old Norse skal "bowl, drinking cup," in plural, "weighing scale" from a noun derivative of Proto-Germanic *skæla "split, divide" (cognates: Old Norse skel "shell," Old English scealu, Old Saxon skala "a bowl (to drink from)," Old High German scala, German Schale "a bowl, dish, cup," Middle Dutch scale, Dutch schaal "drinking cup, bowl, shell, scale of a balance"), from PIE root *skel- (1) "to cut" (see scale (n.1)).

The connecting sense seems to be of half of a bivalve ("split") shell used as a drinking cup or a pan for weighing. But according to Paulus Diaconus the "drinking cup" sense originated from a supposed custom of making goblets from skulls (see skull). Related: Scales. This, as a name for the zodiac constellation Libra, is attested in English from 1630s.

Musical sense (1590s), and the meaning "proportion of a representation to the actual object" (1660s) are via Italian scala, from Latin scala.
scale (v.3): "weigh in scales," 1690s, from scale (n.2). Earlier "to compare, estimate" (c. 1600). Meaning "measure or regulate by a scale" is from 1798, from scale (n.3); that of "weigh out in proper quantities" is from 1841. Scale down "reduce proportionately" is attested from 1887.

Cognate with shallot.
scallop (n.): "bivalve mollusk," c. 1400, from Old French escalope "shell (of a nut), carpace," variant of eschalope, probably from a Germanic source (compare Old Norse skalpr "sheath," Middle Dutch schelpe "shell"); see scale (n.1). The shells of the larger species have been used as domestic utensils. Extended 17c. to objects shaped like scallop shells, especially in design and dress. The verb in the cookery sense, "to bake with sauce in a scallop shell-shaped pan," is attested from 1737. Related: Scalloped; scalloping.
scalp (n.): mid-14c., "top of the head (including hair)," presumably from a Scandinavian source (though exact cognates are wanting) related to Old Norse skalli "a bald head," skalpr "sheath, scabbard,"from the source of scale (n.1).

Meaning "person who re-sells tickets at unauthorized prices for a profit," 1869, American English; earliest reference is to theater tickets, but often used late 19c. of brokers who sold unused portions of railway tickets. [Railways charged less per mile for longer-distance tickets; therefore someone travelling from New York to Chicago could buy a ticket all the way to San Francisco, get out at Chicago and sell it to a scalper, and come away with more money than if he had simply bought a ticket to Chicago; the Chicago scalper would hold the ticket till he found someone looking for a ticket to San Francisco, then sell it to him at a slight advance, but for less than the official price.] Perhaps from scalp (v.); scalper was a generic term for "con man, cheater" in late 19c. Or perhaps the connecting sense is the bounty offered for scalps of certain destructive animals (attested in New England from 1703) and sometimes Indians (i.e., having only part of something, but still getting paid). Some, though, see a connection rather to scalpel, the surgical instrument.
scaly (adj.): also scaley, late 14c., from scale (n.1) + -y (2). Related: Scaliness.
