age-adjusted

The term is a modern compound adjective from the field of statistics and demography. Its first element, "age," traces back to the Latin aetas, which broadly signified a lifetime or generation. The second element, "adjust," originates from the Latin phrase ad iuxta, meaning "to bring near" or "to fit," evolving through French to mean to modify for accuracy. The suffix "-ed" transforms the verbal action into a descriptive state. Thus, the literal construction "age-having-been-modified" logically yields the specialized meaning of a statistical measure that has been altered to account for the influence of age, enabling more equitable comparisons across populations.

Structure: age (state of being) + adjust (alter) + ed (adjective suffix) - age: From Old French aage, eage, ultimately from Latin aetas (period of life, age). Functions as a noun root denoting a period or stage of life. - adjust: From Old French ajoster (to join), from Vulgar Latin adiuxtāre (to bring near), from Latin ad- (to) + iuxtā (near). Functions as a verb root meaning to alter or modify for a purpose. - ed: A common English suffix forming past participles and participial adjectives, from Old English -ed, -od, -ad. Functions as an adjective-forming suffix indicating a state resulting from an action.
