Etymology

The word 'centenary' is built directly upon the Latin numeral 'centum', meaning 'one hundred'. The suffix '-en-' was a common adjectival formative in Latin, which, when combined with the relational suffix '-ary' (from Latin '-arius'), creates a term that literally means 'pertaining to a hundred'. This logical construction passed into English via French, retaining its core numerical reference. Over time, its usage specialized to refer specifically to the marking of a hundred-year period or anniversary, shifting from a general adjective to a term for the commemorative event itself.
