來自PIE*kele,呼喊，呼叫，詞源同call,claim.最早來自公元前6 世紀古羅馬具有傳奇色彩的 偉大首領Servius Tullius 對公民的財產，地位，收入等進行評估（參照census 詞源），并依 據評估結果對公民劃分社會階級（classify），最終形成6 個階級。前5 個階級具有響應國家 軍事號召參軍入伍的資格，而最低等的階級即馬克思理論的無產階級（參照proletarian 詞源） 是不具有這種資格的，他們唯一的使命是為羅馬帝國繁衍后代，在羅馬帝國新占領的領土上 移民聚居。這一改革的結果廢除了古羅馬原有的3 個部落氏族（參照tribe 詞源），使羅馬 由氏族部落過渡到奴隸社會，軍事實力大增。并引申諸多詞義。

class

class: [16] Latin classis originally denoted ‘the people of Rome under arms, the ancient Roman army’; it appears to come from an earlier unrecorded *qladtis, a derivative of the base *qel- ‘call’, which points to an underlying sense ‘call to arms’. Under the terms of the constitution attributed to Servius Tullius, a 6thcentury BC king of Rome, the army, and hence the people, was divided into six such classes, membership of each based originally on the amount of land held, and latterly on wealth in money terms.

English first adopted the word in this antiquarian sense (which provided the basis for the modern application to social class), but its widespread use in the language probably began in the sense ‘group of pupils’. The derivatives classic [17] and classical [16] come from Latin classicus, probably via French classique; in Latin, the adjective signified ‘of the highest class of Roman citizen’, whence the word’s presentday approbatory connotations.

class (n.)

c. 1600, "group of students," from French classe (14c.), from Latin classis "a class, a division; army, fleet," especially "any one of the six orders into which Servius Tullius divided the Roman people for the purpose of taxation;" traditionally originally "the people of Rome under arms" (a sense attested in English from 1650s), and thus akin to calare "to call (to arms)," from PIE root *kele- (2) "to shout" (see claim (v.)). In early use in English also in Latin form classis.

School and university sense of "course, lecture" (1650s) is from the notion of a form or lecture reserved to scholars who had attained a certain level. Natural history sense is from 1753. Meaning "a division of society according to status" (upper, lower, etc.) is from 1772. Meaning "high quality" is from 1847. Class-consciousness (1903) is from German klassenbewusst.

class (v.)

1705, "to divide into classes," from class (n.) or French classer. Sense of "to place into a class" is from 1776. Related: Classed; classing.
