lucre [ˈlukər] n.
1.) Gain, profit, pecuniary advantage. Now only with unfavourable implication: Gain viewed as a low motive for action; ‘pelf’ (O.E.D. 2nd Ed.).
Etymology: adoption (either directly, or through French lucre) of Latin lucrum, from Aryan root lau-, leu-, lou-, whence Greek ἀπολαύειν to enjoy, Gothic launs, Old High German lôn, and Modern German lohn wages, reward.
"For a bisshoppe must be fautelesse as it be commeth the minister of God: not stubborne not angrye no dronkarde no fyghter not geven to filthy lucre: but herberous one that loveth goodnes sobre mynded righteous holy temperat and suche as cleveth unto the true worde of doctryne that he maye be able to exhorte with wholsom learnynge and to improve them that saye agaynst it" (The Epistle of Paul to Titus, William Tyndale (trans.), 1526).
