DID YOU KNOW?

In its original sense, "offal" refers to something that has fallen or been cast away from some process of preparation or manufacture, and it has been used to describe such things as the stalks and dust from tobacco leaves, the less valuable portions of an animal hide, the by-products of milling grain, and the viscera and trimmings of a butchered animal.

The word "offal," however, is not an etymological cast-off, but is an English original that arose in the late 14th century as a combination of "of" (the Middle English spelling of "off") and "fall," aptly naming that which "falls off" or is cast aside from something else.

Since the late 16th century, "offal" has also been used as a synonym for "trash," "garbage," and "rubbish."
