lucre

Etymology

From Middle English lūcre, lucor, lucour, lucur (“gain in money, profit; money; wages; illicit gain; advantage, benefit”), from Old French lucre or Latin lucrum (“advantage, profit; love of gain, avarice”), from Proto-Indo-European *leh₂w- (“gain, profit”) + *-tlom (variant of *-trom (suffix forming nouns denoting tools or instruments)).

noun

1. Money, riches, or wealth, especially when seen as having a corrupting effect or causing greed, or obtained in an underhanded manner.
   When a man bargains for the price of maintaining such or such principles, or of endeavouring to make out such or such a case, without believing in the soundness of the principles or the truth of the case; such a man, whether he touch the cash (or paper-money) before or after the performance of his work, and whether he work with his tongue or his pen, may, I think be fairly charged with seeking after "base lucre;" for he, in such case, manifestly sells not only the use of his talents, but his sincerity into the bargain, and drives a traffic as nearly allied to soul-selling as any thing in this world can be; […] 13 July 1810, William Cobbett, “To the Reader”, in Cobbett’s Weekly Political Register, volume XVIII, number 1, London: Printed by T[homas] C[urson] Hansard, Peterborough Court, Fleet Street; and sold by Richard Bagshaw, Brydges Street, Covent-Garden, and John Budd, Pall-Mall, published 14 July 1810, →OCLC, columns 13–14
