What's the "een" in Halloween?
late 14c., from Latin lucrum "gain, advantage, profit; wealth, riches," from PIE root *lau- "gain, profit" (cf. Greek apo-lanein "to enjoy," Gothic launs, German lohn "wages, reward," and possibly Sanskrit lotam, lotram "booty"). Filthy lucre (Tit. i:11) is Tyndale's rendering of Greek aischron kerdos.
from the Lat. lucrum, "gain." 1 Tim. 3:3, "not given to filthy lucre." Some MSS. have not the word so rendered, and the expression has been omitted in the Revised Version.
