Etymology: In Old English, "sweorfan" meant to scrape, file, or rub a surface until it was smooth or thinned away. It was a strong verb, conjugated by changing its vowel rather than adding an ending, and it belongs to the wider Germanic family of words for scraping and shearing. Its Old English uses were practical, describing the work of smoothing or cutting material down. The verb itself did not survive into Modern English. Its most visible descendant is the noun "swarf," meaning the fine metal shavings or filings produced by cutting or grinding, which is still common in machining. The noun is believed to come from the same Old English root, so a machinist sweeping up swarf is using a word that traces back to the same scraping action the verb once named.
