Denotes a specific language or dialect—the distinctive speech of a people or region, as opposed to generic 'voice' or 'sound.' Classical Greek distinguished dialektos (articulate speech, later a regional variety) from phone (mere sound or voice), and the New Testament preserves this precision. All six occurrences appear in Acts, where language identity matters deeply for the spread of the gospel. The field bought with Judas's blood was called Akeldama 'in their dialect' (Acts 1:19). At Pentecost, the crowd is astonished because each person hears the apostles speaking 'in his own dialect' (Acts 2:6, 8). Paul addresses the Jerusalem crowd 'in the Hebrew dialect' (Acts 21:40; 22:2; 26:14), earning their attentive silence. Spanish 'lengua,' French 'dialecte,' and German cognates all point to the idea of a regionally or ethnically specific tongue.
