(sis-uh-ROH-nee)
(n.)A guide for sightseers

One of ancient Rome's most notable orators was Marcus Tullius Cicero (106-43 BC). Now, to understand why he was called "Cicero," you have to understand that in antiquity, a lot of folks were named for their physical characteristics; "Crassus," for example, meant "fat." In the case of "Cicero", this name derives from Latin "cicer," meaning "chickpea"--a reference to the fact that he had a chickpea-shaped wart on the end of his nose.

Anyway, a cicerone is a guide who likewise orates to a group of sightseers.

By the way, if you want to sound even more authentically Italian (and perhaps more cicerone-like in the process), you can also pronounce this word "chich-uh-RAH-neh" or "chee-cheh-RAH-neh."

"But my all-time favorite cicerone is the one in 'Pee-Wee's Big Adventure'--you know, the one who leads tourists through the Alamo and sweetly asks, 'Can you say 'adobe'?'"
