"ol" is the actual building, only (whether the one in Washington, D.C. or a state capital), everything else is "al". That's why I don't like/use spell check; I assume over the years it will get better at such things, be able to infer stuff from surrounding text, etc. but sometimes my cell phone drives me batty with its recommendations when I'm texting; fortunately my new one doesn't just automatically insert whatever it feels like so I have to be vigilant; I can just ignore it instead. I do feel superior to all spell check programs and enjoy that I don't have to feel guilty for feeling that way
