somersault

From French sombresault (now obsolete, compare French sursaut, soubresaut), from Old Occitan sobresalt, from sobre- (“over, above”) + salt (“jump”), from Latin suprā (“over”) + saltus (“jump”). Doublet of soubresaut. Cognate with Spanish sobresaltar (“to spook, startle”) and Portuguese sobressaltar (“to spook, scare, jump over”).
