mass-transit

The term "mass-transit" is a modern compound noun formed in the late 19th to early 20th century, coinciding with the rise of industrialized urban public transportation systems. The first element, "mass," draws from its Latin root massa, which evolved from Greek maza (barley cake, lump), to signify a large, collective body of people. The second element, "transit," originates from the Latin verb transire, meaning "to go across," reflecting the core function of movement. The compound logically fuses these concepts to denote a transportation system specifically engineered for the efficient passage of large crowds, distinguishing it from private, individual conveyance.

Structure: mass (large quantity) + transit (passage) - mass: From Latin massa (a lump, bulk, mass). In this compound, it functions as an attributive noun meaning "involving or for a large quantity of people." - transit: From Latin transitus (a going across, passage), from transire (to go across). It functions as the head noun meaning "transportation or passage."
