Root / Etymology

From the root ἔθω, meaning 'to be accustomed, to be in the habit of.' ἔθος is the nominal form denoting 'custom' or 'habit.' Cognate with Latin 'ethos' and later English 'ethics,' though the semantic field shifted in later philosophical usage.

Historical & Contextual Notes

έθος appears in classical Greek (e.g., Herodotus, Plato) to designate custom, habit, or established usage, often in contrast to written law (νόμος). In Hellenistic and Roman periods, including the New Testament and Septuagint, it denotes practices, especially those defining group identity—such as religious rituals, dietary customs, or civic observances. It can refer to practices unique to different peoples (cf. usage in Luke 1:9; Acts 6:14; 15:1), and is sometimes contrasted with divine command or written statute. While often translated as 'custom' or 'manner' in English Bibles, these renderings do not always capture the nuance that ἔθος can also signal binding collective traditions with a force similar to law. Its semantic overlap with νόμος ('law') sometimes results in their complementarity or tension within Greco-Roman and early Judean discourse. Over time, especially in philosophical literature, ἔθος became associated with character formation and ethics, but in the biblical period retains its focus on collective or habitual practice.

Original Strong's Gloss (1890)

from ἔθω; a usage (prescribed by habit or law):--custom, manner, be wont.
