"What's the beef?"

The Oxford American Dictionary(1980) contains the following definition:

Brand (noun): a trade mark, goods of a particular make: a mark of identification made with a hot iron, the iron used for this: a piece of burning or charred wood, (verb): to mark with a hot iron, or to label with a trade mark.

Similarly, The Pocket Oxford Dictionary of Current English(1934) says:

Brand. 1. n. Piece of burning or smouldering wood, torch, (literary); sword (poet.); iron stamp used red-hot to leave an indelible mark, mark left by it, stigma, trade-mark, particular kind of goods (all of the best bb.). 2. v.t. Stamp (mark, object, skin), with b., impress indelibly (is branded on my memory)

These two entries, in the order in which they list the definitions and in the definitions themselves, illustrate how, over 50 years, the primary use of the word “brand” now has a commercial application. However, the definitions also underline a common origin. Almost irrespective of how the word is used today, it has always meant, in its passive form, the object by which an impression is formed, and in its active form the process of forming this impression…
