"one who grinds grain in a mill," mid-14c. (as a surname by early 14c.), agent noun from mill (v.1). In Middle English both with and without the -n-. The Old English word was mylnweard, literally "mill-keeper" (preserved in surname Millward, which is attested from late 13c.).
"stale joke," 1816, from Joseph Miller (1684-1738), a comedian, whose name was affixed after his death to a popular jest-book, "Joe Miller's Jests, or the Wit's Vade-mecum" (1739) compiled by John Mottley, which gave Miller after his death more fame than he enjoyed while alive.
A certain Lady finding her Husband somewhat too familiar with her Chamber-maid, turned her away immediately; Hussy, said she, I have no Occasion for such Sluts as you, only to do that Work which I choose to do myself. [from "Joe Miller's Jests"].
Doctor Kearney, who formerly, with so much reputation, delivered lectures in this place on the history of Rome, observed to me once, that he was not an optimist, but an "agathist"; that he believed that every thing tended to good, but did not think himself competent to determine what was absolutely the best. The distinction is important, and seems to be fatal to the system of Optimism. [George Miller, "Lectures on the Philosophy of Modern History," Dublin, 1816]
mid-15c., "the profit arising from office or employment, that which is given as compensation for services," from Old French émolument "advantage, gain, benefit; income, revenue" (13c.) and directly from Latin emolumentum "profit, gain, advantage, benefit," perhaps originally "payment to a miller for grinding corn," from emolere "grind out," from assimilated form of ex "out" (see ex-) + molere "to grind" (from PIE root *mele- "to crush, grind"). Formerly also "profit, advantage, gain in general, that which promotes the good of any person or thing" (1630s).
Hymnal measure (a quatrain, usually iambic, alternately rhymed) is so called for being the preferred verse form for English hymns (such as "Amazing Grace"). It has been popular in English secular poetry as well, "though it almost always suggests the hymn, directly or ironically" [Miller Williams, "Patterns of Poetry," 1986].
the earlier form of poulterer (q.v.). Poetic poulter's measure (1570s), a combination of lines of 12 and 14 syllables, is said to be so called for suggesting "the poulter's old practice of giving an extra egg with the second dozen." [Miller Williams, "Patterns of Poetry," 1986].
The commonest sort of verse which we vse now adayes (viz. the long verse of twelue and fourtene sillables) I know not certainly howe to name it, vnlesse I should say that it doth consist of Poulter's measure, which giueth xii. for one dozen and xiiij. for another. [George Gascoigne]
