multitude

From Middle English multitude, multitud, multytude (“(great) amount or number of people or things; multitudinous”), borrowed from Old French multitude (“crowd of people; diversity, wide range”), or directly from its etymon Latin multitūdō (“great amount or number of people or things”), from multus (“many; much”) + -tūdō (suffix forming abstract nouns indicating a state or condition). The English word is analysable as multi- +‎ -itude.
