Definition of rancid

rancidadjective

ôi

/ˈrænsɪd//ˈrænsɪd/

The word "rancid" comes from the Old French word "ranc," which translated to English means "sour" or " bitter." During the Middle Ages, the word specifically referred to the spoilage of animal fats, such as those used in cooking and lighting. As animal fats were an important resource for daily life during this time, people began noticing that fats left exposed to air and heat would eventually turn sour and develop a foul odor. This process, known as "rancidity," was a result of the breakdown of the fatty acids in the fat by enzymes or bacteria. The word "rancid" was officially adopted into the English language in the 16th century and still carries its original meaning today. It is commonly used to describe spoiled fats used in cooking, such as rancid butter, as well as other substances that degrade over time and develop unpleasant odors or flavors, such as rancid oils or medications.
