Etymology: The most striking thing about "swarf" is that it shares a root with "swerve," a word about turning aside. Its ancestor, Proto-Germanic "swerbaną," meant "to mop, wipe, or rub off," and the shavings it named were literally what got rubbed away. Old English "sweorfan" meant "to rub, scour, or file," and the noun grew from that action: the fine metal dust left behind by filing or scouring. Medieval English kept the idea of metal dust and rust. Old English "ġesweorf" referred to iron filings and rust, while the Old Norse "svarf" meant metallic dust, and the two likely reinforced each other as the word settled into English. The sense of "shavings from machining" came much later, once cutting and grinding became everyday industrial work. Meanwhile the verb branch took a different path. Middle English "swerven" gathered meanings of wandering, staggering, and turning aside, which became the modern "swerve." The two words are cousins that split apart: one describes the rubbing that leaves dust behind, the other the sideways movement of something that has been pushed off course.

Synonyms: metal shavings, filings
