Eniautos denotes a complete year and carries a slightly more formal or cyclical connotation than the more common etos. In classical Greek it originally meant 'anniversary' or 'cycle' (from eni + autos, 'returning upon itself'), and this cyclical flavor persists in its New Testament usage. Hebrews uses it repeatedly for the annual Day of Atonement ritual — the high priest entering the Most Holy Place 'once every year' (Heb 9:7, 10:1, 10:3) — where the yearly repetition underscores the insufficiency that Christ's once-for-all sacrifice resolves. John's Gospel notes that Caiaphas was high priest 'that year' (John 11:49, 51; 18:13), loading a simple temporal marker with dramatic irony. Spanish 'ano,' French 'annee,' and German 'Jahr' render it without distinction from etos, though the Greek preserves a subtle emphasis on the year as a completed cycle.
