The Guardian· 27 Aug 2026

Circa 1525, borrowed from Middle Dutch splissen (Modern Dutch splitsen); akin to Middle Dutch splitten (“to split”), German spleißen (“to split, splice”), Spliss (“split ends, hair breakage”), French épisser (also from Dutch). The Dutch word originally referred only to the fraying of the ropes' ends but was then also used for the entire process of fraying and retying; hence the peculiar semantic development from “split” to “join”. The same development occurred in German.
