Is a hot dog a sandwich?

[Loony BoB]

This has already been covered. The sub sandwich is largely considered a sandwich. It's one piece of bread. So are gyros, and perhaps wraps. One piece of bread.

If you ask for a sandwich and you get a hot dog or a wrap, you know you're not getting what you asked for. Everyone calls them hot dogs, not sandwiches, for a reason. I'm pretty sure this falls in line with "largely considered" things. I do not know of anyone who calls a hot dog a sandwich, nor a wrap.

I submit for exhibit B, the open-faced sandwich. Traditionally served on a single piece of sandwich bread with toppings. Yet still in the sandwich family.

I can link you to a lot of things that, by name, are in a [word] family but are actually not a [same word]. A hot dog, for example, is not actually a dog despite it having dog in the name. A sandwich by technicality and definition involves two pieces of bread. Wikipedia gets trumped by the almighty powers of the dictionary.
