Origin of eclatFrench, brilliance, from Old French esclat, splinter, from esclater, to burst out, splinter, probably of Germanic origin.
Borrowing from French, from éclater (“to burst out”), from Middle French esclater (“to break, break violently”), from Old French esclater (“to separate from, sunder out”) (deverbal also in Old French: esclat), from Frankish *slaitan (“to split, break”), from Proto-Germanic *slaitijaną, causative of Proto-Germanic *slītaną (“to cut up, split”). Akin to Old High German sleizan (“to tear”), Old English slītan (“to split”). More at slice, slit.
