The term "effective majority" refers to a group or coalition that holds enough votes or support within a larger body, such as a legislative assembly, to influence or determine outcomes. This means that even if they do not make up a numerical majority of the total members, their vote can still have a significant impact on decisions and actions due to their ability to persuade others or form alliances with other groups. In essence, an effective majority is one that can effectively wield power despite being in the minority in terms of numbers.
