allyoudaoicibaDictYouDict[all 词源字典]
Old English eall "all, every, entire," from Proto-Germanic *alnaz (cognates: Old Frisian, Old High German al, Old Norse allr, Gothic alls), with no certain connection outside Germanic.

Combinations with all meaning "wholly, without limit" were common in Old English (such as eall-halig "all-holy," eall-mihtig "all-mighty") and the method continued to form new compound words throughout the history of English. First record of all out "to one's full powers" is 1880. All-terrain vehicle first recorded 1968. All clear as a signal of "no danger" is recorded from 1902. All right, indicative of approval, is attested from 1953.[all etymology, all origin, 英语词源]

girl (n.)youdaoicibaDictYouDict
c. 1300, gyrle "child, young person" (of either sex but most frequently of females), of unknown origin. One guess [OED] leans toward an unrecorded Old English *gyrele, from Proto-Germanic *gurwilon-, diminutive of *gurwjoz (apparently also represented by Low German gære "boy, girl," Norwegian dialectal gorre, Swedish dialectal gurre "small child," though the exact relationship, if any, between all these is obscure), from PIE *ghwrgh-, also found in Greek parthenos "virgin." But this involves some objectionable philology. Liberman (2008) writes:
Girl does not go back to any Old English or Old Germanic form. It is part of a large group of Germanic words whose root begins with a g or k and ends in r. The final consonant in girl is a diminutive suffix. The g-r words denote young animals, children, and all kinds of creatures considered immature, worthless, or past their prime.
Another candidate is Old English gierela "garment" (for possible sense evolution in this theory, compare brat). A former folk-etymology derivation from Latin garrulus "chattering, talkative" is now discarded. Like boy, lass, lad it is of more or less obscure origin. "Probably most of them arose as jocular transferred uses of words that had originally different meaning" [OED]. Specific meaning of "female child" is late 14c. Applied to "any young unmarried woman" since mid-15c. Meaning "sweetheart" is from 1640s. Old girl in reference to a woman of any age is recorded from 1826. Girl next door as a type of unflashy attractiveness is recorded by 1953.
Doris [Day] was a big vocalist even before she hit the movies in 1948. There, as the latest movie colony "girl next door," sunny-faced Doris soon became a leading movie attraction as well as the world's top female recording star. "She's the girl next door, all right," said one Hollywood admirer. "Next door to the bank." ["Life" magazine, Dec. 22, 1958]
Girl Friday "resourceful young woman assistant" is from 1940, a reference to "Robinson Crusoe." Girl Scout is from 1909. For the usual Old English word, see maiden.
hunky-dory (adj.)youdaoicibaDictYouDict
1866, American English (popularized c. 1870 by a Christy Minstrel song), perhaps a reduplication of hunkey "all right, satisfactory" (1861), from hunk "in a safe position" (1847) New York City slang, from Dutch honk "goal, home," from Middle Dutch honc "place of refuge, hiding place." A theory from 1876, however, traces it to Honcho dori, said to be a street in Yokohama, Japan, where sailors went for diversions of the sort sailors enjoy.
rinky-dink (adj.)youdaoicibaDictYouDict
1913 (from 1912 as a noun), said to be carnival slang and imitative of the sound of banjo music at parades [Barnhart]; compare ricky-tick "old-fashioned jazz" (1938). But early records suggest otherwise unless there are two words. The earliest senses seem to be as a noun, "maltreatment," especially robbery:
So I felt and saw that I was robbed and I went to look after an officer. I found an officer on the corner of Twenty-fifth street and Sixth avenue. I said, "Officer, I have got the rinky-dink." He knew what it meant all right. He said, "Where? Down at that wench house?" I said, "I guess that is right." [testimony dated New York August 9, 1899, published 1900]
And this chorus from the "Yale Literary Magazine," Feb. 1896:
Rinky dinky, rinky dink,
Stand him up for another drink.
