Derived from κτάομαι ('to acquire'), this noun denotes a concrete possession—something gotten and held as property. In classical Greek it could refer to any acquired asset, from slaves to heirlooms, but in the NT it appears in contexts of landed wealth. The rich young man went away sorrowful because he had many κτήματα (Matt 19:22; Mark 10:22), and the early Jerusalem believers sold their possessions and distributed the proceeds (Acts 2:45; 5:1). Spanish propiedades and German Besitz both highlight the tangible, material nature of these holdings.
