what is the meaning of hamburger

hamburger is a sandwich (in the United Kingdom, South Africa and Saudi Arabia, the patty alone is known as a beefburger or burger) that consists of a patty of ground meat that is usually beef. The meat can be grilled, fried, steamed, or broiled, and is generally served with various condiments and toppings inside a bun baked specially for this purpose. Burgers are often served with french fries, potato chips, or onion rings.

Hamburger can also refer to the meat itself. This type of meat can be used in boxed dinners such as "Hamburger Helper". Hamburger is actually a distinct product from ground round and other types of ground meat. However, ground beef of any form is often commonly referred to as "hamburger." A recipe calling for 'hamburger' (the non-countable noun) would require ground beef or beef substitute- not a whole sandwich.
