Etymology

Origin of testimony

First recorded in 1350–1400; Middle English, from Latin testimōnium, equivalent to testi(s) “witness” + -mōnium noun suffix; see -mony

Explanation

When you give testimony you are telling what you saw or what you know. Your testimony that your hand was not in the cookie jar goes against the testimony of several eyewitnesses. The Latin root for testimony is testis, meaning “ witness.” “Eye witness testimony” is a phrase you will hear often in legal discussions. An object can also give testimony, without speaking of course: "The statue they built of you outside the bowling alley offers testimony to your greatness."
