centurys

Centurys is not the standard English form for the plural of century. In contemporary usage, the correct plural is centuries. The spelling centurys typically arises as a misspelling or nonstandard variant, though it may appear as a proper noun in fictional settings or branding.

Etymology and historical usage: The word century comes from Old French centurie, via Latin centuria from centum meaning “one hundred.” In Latin, the plural was centuriae; in English, centuries is the normal plural. A century is a period of about 100 years and is used to organize historical time, as in “the 18th century.” In ancient Rome, a centuria was a military unit of roughly one hundred men, commanded by a centurion; the term influenced later usage of the word century as a time span.

Usage notes: In formal writing, use centuries for multiples of 100 years (two centuries, five centuries). The possessive forms are century’s for a single century and centuries’ for multiple centuries. The form centurys should be avoided unless it appears as a deliberate branding or fictional name.

Proper noun usage: Some authors or organizations may adopt Centurys as a proper name, such as a fictional place, product line, or group. In such cases, capitalization signals a specific entity rather than a standard plural, and the spelling reflects branding choices rather than grammar.

Summary: While centurys may appear in certain nonstandard or named contexts, the legitimate plural of century in English is centuries. The term has historical roots in Latin and Roman military usage, and remains a common unit for dating and describing long periods in history.
