century-long

the compound "century-long" is a modern english formation, combining the noun "century," derived from latin 'centuria' (a unit of one hundred, especially of soldiers or years), with the adjective "long," from old english 'lang,' meaning of great duration. the latin 'centuria' itself originates from 'centum,' the proto-indo-European root for "hundred." the logic of the compound is transparently descriptive, directly linking the specific time span of a century to the enduring quality denoted by "long." it follows a common english pattern for creating compound adjectives that specify duration, such as "day-long" or "month-long," to describe events or states persisting for the indicated period.

Structure: century (hundred years) + long (lasting) - century: from latin 'centuria', meaning a group of one hundred. in this compound, it denotes the unit of time (a hundred years). - long: from old english 'lang, long', meaning having great duration or extent. in this compound, it functions as an adjective meaning 'lasting for'.
