The word "attest" traces back to Latin attestari, combining ad- (toward) and testari (to bear witness). Historically, it referred to calling witnesses to validate statements or events. Over time, it broadened to mean any formal or evidentiary confirmation. The root test- also appears in words like "testify" and "testimony," preserving its legal and verificational core.
