Definition of smudge

The origin of the word "smudge" can be traced back to the Old English word "smōð," which means "stain" or "mark." This word evolved from an earlier Germanic root, "smug-, smugdan," which means "to mark" or "to smear." In Middle English, the term "smādge" or "smaught" was used to describe a mark, stain, or smear, often made with dirt, soot, or other substances. This meaning of the word continued into Early Modern English. As the use of candles and incense became more common in religious ceremonies, a new meaning for "smudge" emerged. In the 18th century, "smudging" came to refer to the act of blowing out or extinguishing a candle or other flame with smoke or unpleasant-smelling substances, such as former times tobacco and sulfur smoke was blown over a person to ward f demon spirits. This action was often done as part of religious rituals. Over time, the term "smudge" has also been applied to various other contexts. In the early 20th century, "smudge" was used to describe a blurry or indistinct image. Today, the term is also used in sports, such as in the phrase "smudge pot," a device used by farmers to ward off frost. In modern usage, "smudge" most commonly refers to the mark left by smudged ink on paper, fingerprints, or other stains or marks on surfaces.
