I wanted my daughter's middle name to be "Lone Wolf". You don't need a middle name anyway, so you may as well have fun with it.
That way, *if* she wanted, she could either go by Sophia, or LONE WOLF!!!!!. Personally, I'd go with Lone Wolf. Unfortunatly, my wife doesn't seem to share my practical sensibilities, seeks to deny our child options when it comes to name choices, and apparently has no sense of humor.
More to the point: My general rule of thumb is that if the word is a verb, noun, adjective, adverb, etc, then it's not a name. Now, there are, of course, some exceptions such as Bob, Bill, etc, but generally speaking, a name can't be used in a sentence as anything other than a name.
"Holiday" isn't a name, it's a noun.
"Summer" isn't a name, it's a season.
"Peaches" isn't a name, it's a stripper.
