A — 1: ἁμαρτία
(Strong's #266 — Noun Feminine — hamartia — ham-ar-tee'-ah )

is, lit., "a missing of the mark," but this etymological meaning is largely lost sight of in the NT. It is the most comprehensive term for moral obliquity. It is used of "sin" as (a) a principle or source of action, or an inward element producing acts, e.g., Romans 3:9; 5:12,13,20; 6:1,2; 7:7 (abstract for concrete); 7:8 (twice),9,11,13, "sin, that it might be shown to be sin," i.e., "sin became death to me, that it might be exposed in its heinous character:" in the clause, "sin might become exceeding sinful," i.e., through the holiness of the Law, the true nature of sin was designed to be manifested to the conscience;
