Aerial. It can be an adjective- "We took some aerial photography" or a noun- "She did an aerial in gymnastics".
Evidently, it can also be a first name.
I don't have any problem with Ariel as a first name. Sure, it was originally masculine, and I have issues with the angelic type names, but MY kid is named after The Little Mermaid, too, so I really can't say anything there. (No, it's not Ariel. Or Triton. Or Ursula.) But...Aerial? I mean, if you must misspell the name, couldn't you misspell it in a way that doesn't suggest another word?
Meh. Evidently not, for Aerial's parents. Maybe she'll grow up to be a gymnast or a photographer.
