flying - VOR radials/intersections and ""how do you spell ...?

Today, while studying for the upcoming ground school test, I've been listening to Potomac ATC. For the first time I've heard at least 5 pilots ask for the spelling of the TICON airspace fix when they were directed to it. I tried to find it on my chart and had no luck (so I'm assuming that the pilots were doing the same). I also came to the revelation (I think it's correct) that the Victor airways are just matching VOR radials.
