Definition of swab

The word "swab" has originated from an Old Norse word "skofi" which means "wiping cloth." This word eventually made its way into Middle Low German, where it transformed into "schoof" and subsequently "schuf," meaning "broom" or "a instrument used for cleaning." The term "swab" emerged during the 17th century, when it came to refer to a stick or broom used for cleaning barrels or other containers. The etymology of the term is related to the use of a broom or a whisk made of fibers to remove impurities from within the barrels during the fermentation process. During the 19th century, "swab" came to be associated with medical settings, particularly in reference to a sterile cotton or gauze applicator used to absorb fluids or clean wounds. This use of the term is still prevalent today, particularly in medical contexts, where the word "swab" is commonly used to refer to a tool used for swabbing and sterilizing surfaces. So, to summarize, the word "swab" originated from an Old Norse word meaning "wiping cloth," and has evolved over time to refer to various instruments and tools used for cleaning and sterilization.
