This noun denotes a turning or wheeling about—a change of direction or orientation. In Acts 15:3, it describes the conversion of the Gentiles, their turning from idols to God. Classical Greek used this word for ships putting about, soldiers wheeling in formation, or rivers winding. The New Testament appropriates this spatial language for spiritual reorientation. The multilingual evidence shows interpretive choices: Spanish conversión and French conversion make the theological meaning explicit, while the Greek term itself is more neutral—simply a turning that context makes spiritual.
