Picture an English sawmill in the 1300s: a broad, stubborn slice of timber comes off the log, too thick to bend and too useful to discard. Someone called it a *sclabbe* or *slabbe*, but nobody knows exactly where that chunky word came from. One theory links it to a Germanic family connected with “slippery” and smooth timber; another connects it with Celtic words for a splinter or chip, though the Oxford English Dictionary rejects that route on formal grounds. By the 1570s, a slab could specifically mean the outside cut of a tree, and in 1927 it acquired its modern construction sense: a rectangular block of precast concrete. So a word of uncertain birth now names everything from a gravestone to a skyscraper floor—and, in Australian slang, even a carton of beer.
