μαμωνᾷ. [4 verses](noun sg masc dat) "Mammon" is not Greek. It could be from the Aramaic mamona, "riches" or "wealth," or from Hebrew mamon, "security," "that which is trusted," or "deposit" or from Akkardian "mimmu" meaning "property." -- (UW) "Mammon" is not from any Greek word, but it is a word that is untranslated from the Greek letters of the sources. There is some debate about both its source and its meaning.  The Aramaic source words mean "wealth" and "money," but Jesus readily uses the Greek words for wealth and for money, both generally and specifically.  From the context in which he uses it, he seems to used it to refer to ill-gotten gains, that is, plunder or loot.
