Testimonial → It is formed from "testis" (meaning witness) and the suffix "-al" (meaning pertaining to). The word refers to something that pertains to a witness or testimony, often used to describe a statement that supports a claim or assertion.
Think of a 'witness' ('testis') providing a statement that is 'pertaining to' ('-al') their experience — that's why a testimonial is a statement of support.
