Definitions
Synonym of ethics (“the study of principles relating to right and wrong conduct”).
Word origin
Learned borrowing from Ancient Greek δέον (déon, “that which is binding, needful, proper, or right”) + English -ology (variant of -logy (suffix denoting a branch of learning or a study of a particular subject)). Δέον (Déon) is the neuter present participle of δεῖ (deî, “it behoves one to, it is necessary to, one must”), from δέω (déō, “to bind, tie; to fasten; to fetter”), ultimately from Proto-Indo-European *deh₁- (“to bind”).
