This noun denotes desire, appetite, or longing—a reaching out toward an object of want. It's the general Greek term for appetency or conation, encompassing various forms of desire. In Romans 1:27, it describes illicit sexual desire: 'the men, giving up natural relations with women, were consumed with desire for one another.' The word emphasizes intensity—they were 'burned with desire' or 'consumed by longing.' While the term can be neutral (desire for good things), here it describes disordered passion that violates created design.
