A hamburger (also called a hamburger
sandwich, burger or hamburg) is a sandwich consisting
of a cooked patty of ground meat (usually beef,
but occasionally pork or a combination of meats)
usually placed inside a sliced bread roll. Hamburgers
are often served with lettuce, bacon, tomato, onion,
pickles, cheese and condiments such as mustard,
mayonnaise, ketchup and relish.
The term "burger", can also be applied
to the meat patty on its own, especially in the
UK where the term "patty" is rarely used.
The term may be prefixed with the type of meat as
in "beef burger".
The term hamburger originally derives from Hamburg,
Germany's second largest city, from where many people
emigrated to the United States. In High German,
Burg means fortified settlement or fortified refuge;
and is a widespread component of place names. Hamburger
can be a descriptive noun in German, referring to
someone from Hamburg (compare London to Londoner)
or an adjective describing something from Hamburg.
Similarly, frankfurter and wiener, names for other
meat-based foods, are also used in Germany and Austria
as descriptive nouns for people and as adjectives
for things from the cities of Frankfurt and Wien
(Vienna), respectively. The term "burger"
is associated with many different types of sandwiches
similar to a (ground beef) hamburger, using different
meats, such as a buffalo burger, venison, kangaroo,
turkey, elk, salmon burger or veggie burger.
