Did you know?

Lightning strikes more than once in the history of fulminate. That word comes from the Latin fulminare, meaning "to strike," a verb usually used to refer to lightning strikes—it is struck from fulmen, Latin for "lightning." When fulminate was taken up by English speakers in the 15th century, it lost much of its ancestral thunder and was used largely as a technical term for the issuing of formal denunciations by ecclesiastical authorities. In time, its original lightning spark returned, describing intense strikes of a tirade.
