[French majorité, from Medieval Latin māiōritās, from Latin māior, greater; see meg- in the Appendix of Indo-European roots.]
Usage Note: When majority refers to a particular number of votes, it takes a singular verb: Her majority was five votes. His majority has been growing by 5 percent every year. When it refers to a group of persons or things that are in the majority, it may take either a singular or plural verb, depending on whether the group is considered as a whole or as a set of people considered individually. So we say The majority elects (not elect) the candidate it wants (not they want), since the election is accomplished by the group as a whole; but The majority of the voters live (not lives) in the city, since living in the city is something that each voter does individually. · Majority is often preceded by great (but not by greater) in expressing emphatically the sense of "most of": The great majority approved. The phrase greater majority is appropriate only when considering two majorities: He won by a greater majority in this election than in the last.
