ˌSuper ˈTuesday
in the US, the second Tuesday in March during a year when there is an election for the position of President. Before the main election in November, there is a series of ‘primaries’ (primary), in which the people in each state choose the person that they want as their party’s candidate for President. These primaries take place in the first six months of the year, but on Super Tuesday there are several important primaries all on the same day.
