Origin
The word "testation" comes from the Latin word testatio, which means "witnessing" or "evidence." This word is derived from the Proto-Indo-European root *tést- ("to witness"). This root also gives rise to the words "testify," "testimony," and "testament."
The word "testation" was first used in English in the 14th century. It was originally used to refer to the act of witnessing or providing evidence in a legal proceeding. Over time, the word has come to be used in a more general sense, referring to any statement or declaration that serves as evidence or proof.
