'ta-da' originates from English, specifically the imitative exclamation 'ta-dah', where it imitated the sound of a brief fanfare or musical flourish.

'ta-da' changed from 19th-century stage exclamation 'ta-dah' and eventually became the modern English interjection 'ta-da' used in informal speech.

Initially, it meant 'an imitative sound suggesting a fanfare or flourish', but over time it evolved into its current meaning of 'a spoken exclamation used to highlight a reveal, success, or surprise'.
