digit-, digiti-

(Latin: finger, toe; from Greek daktylos)

digitus impudicus
"Giving the bird" or "the finger"; a gesture using the middle finger to simulate a penis, and the remaining fingers to represent the testicles.

The origin of this gesture is considered to be speculative, but it is quite possibly up to 2500 years old.

It is identified as the digitus impudicus, "impudent finger" in Ancient Roman writings and reference is made to using the finger in the Ancient Greek comedy, The Clouds, by Aristophanes. It was defined there as a gesture intended to insult someone.
