eleventh-grade

The term is a modern American English compound adjective precisely denoting an academic level. Its first element, 'eleven', originates from the Old English concept of "one left over" after counting to ten. The ordinal suffix '-th' solidifies its sequential position. The final element, 'grade', descended from the Latin gradus (a step), evolved through French to signify a stage of progression. Combined, these morphemes logically construct the meaning: the specific step or year which is ordinally the eleventh.
