somersault: [16] Somersaults have no connection with ‘summer’. The first element of the word means etymologically ‘over’. It comes from Old French sombresault, an alteration of an earlier sobresault. And this in turn was acquired from Provençal *sobresaut, a compound formed from sobre ‘over, above’ (a descendant of Latin sūpra) and saut ‘jump’ (a descendant of Latin saltus, which has close relatives in English assault, insult, sauté, etc).
=> assault, insult, result, sauté
