What is Testify?
1.
1. To give one's information "as truthfully as possible." Taken from an old Roman phrase "to swear on one's testicles." Now, think about that, and think about how differently court cases would turn out if that meaning held true to this day...
"Testify" is usually used in reference to a court setting or a confession of some sort.

You two are wrong. "Testify" comes from the Latin "witness" and has nothing to do with "testicle" which also comes from the Latin for "witness". I was asked this in class by the professor in college English. I would have been wrong and embarrassed myself, so I just said "I don't know". But here's what I got from the Internet:
testatio -onis f. calling to witness , or bearing witness.
testificatio -onis f. bearing witness , testifying; evidence, proof.
testificor -ari dep. to bear witness to , give evidence of; to show, bring to light; to call to witness.
testimonium -i n. witness , evidence; proof, indication.
testis (1) -is c. one who gives evidence , a witness; an eye-witness, a spectator.
testor -ari dep. (1) to bear witness to , give evidence of; to make known, publish, declare; as pass. to be attested, declared. (2) to make a will. (3) to call to witness.
BTW they are called "testicles" because they WITNESS to the procreative power of a man.
Since I was a witness to the crime, they want me to testify in court.
