grasping for more: the restless drive to have more than one's fair share, always at someone else's expense
The word is built from the Greek for "more" and "to have," so at root it means "having-more-ness": the drive to grasp more than one's rightful portion. What sets it apart from a broader word for craving (ἐπιθυμία), and from the love of money that simply hoards (φιλαργυρία), is that this word is measured against other people. To want more is to want more than someone else has, or more than is fair, so the greedy person's gain is always another's loss.
That relational core lets the word swing between two poles that were never really separate in the ancient mind. It can name an inward appetite, the insatiable heart that always wants more, and it can name the outward act, the defrauding or extortion by which that appetite reaches out and takes. English usually needs different words for the two ("greed" for the disposition, "extortion" for the deed), which is one reason a single translation never quite holds the whole word.
Its most startling turn is theological. Twice the New Testament flatly calls greed idolatry (Colossians 3:5; Ephesians 5:5), singling it out from the sins around it. The background is a Jewish conviction, already old by Paul's day, that whatever you love, trust, and serve above God has become your god, and for most people that rival is money. So this is not a minor fault in the biblical picture but a diagnosis of the heart: the quiet drive to have more is the drive to be one's own god.

Whether πλεονεξία carries a sexual sense (a grasping lust for what belongs to another) when Paul lists it beside sexual sins, or always denotes economic greed as a separate vice.
- majorityIt denotes material greed even in these lists; Paul moves from sexual sins to a distinct sin of acquisitiveness, mirroring the Jewish grouping of idolatry, sexual sin, and greed.; Brian S. Rosner, Greed as Idolatry (Eerdmans, 2007), ch. 8; Andrew T. Lincoln, Ephesians (WBC 42, 1990); Ernest Best, Ephesians (ICC, 1998)
- minorityIn the immediate context of sexual immorality the word shades into a sexual grasping, coveting a neighbor's spouse alongside the goods of the tenth commandment.; T. K. Abbott, Ephesians and Colossians (ICC, 1897); Markus Barth, Ephesians (Anchor Bible, 1974)
