"youth, lad; boy of the lower orders; personal servant," c. 1300 (early 13c. as a surname), originally also "youth preparing to be a knight" (beneath the rank of a squire), from Old French page "a youth, page, servant" (13c.), possibly via Italian paggio (Barnhart), from Medieval Latin pagius "servant," perhaps ultimately from Greek paidion "boy, lad," diminutive of pais (genitive paidos) "child."
But OED considers this unlikely and, with Century Dictionary, points instead to Littré's suggestion of a source in Latin pagus "countryside," in sense of "boy from the rural regions" (see pagan). Meaning "youth employed as a personal attendant to a person of rank" is first recorded mid-15c.; this was transferred from late 18c. to boys who did personal errands in hotels, clubs, etc., also in U.S. legislatures.
c. 1200 (late 12c. in surnames), grome "male child, boy;" c. 1300, "a youth, young man," also "male servant, attendant, minor officer in a royal or noble household ranking higher than a page; a knight's squire." A word of unknown origin with no certain cognates in other Germanic languages.
Perhaps it is from an unrecorded Old English *grom, *groma, which could be related to growan "to grow," and influenced by guma "man." Or perhaps it is from or influenced by Old French grommet "boy, young man in service, serving-man" (compare Middle English gromet "ship's boy," early 13c.). As the title of an officer of the English royal house from mid-15c. The specific meaning "male servant who attends to horses and stables" is from 1660s, from earlier combinations such as horse-groom, Groom of the Stables, etc.
It was on a side hill, and I observed a boy, who appeared to be about fifteen years of age, opposite the house felling a large tree; he had cut a few chips from the under side, and was then making the principal incision on the upper. ... I said to the boy, "Well Sir, I see that you make the upper cut." "That is the true cut," said the boy; "for if you will take the axe and try below, you will find that the tree will crowd down upon your chips, and you can't get it down in double the time."
