Word Nuance & Usage

While "frivolousness" and "frivolity" are near-exact synonyms, "frivolity" is considerably more common in modern English and can also be used in the plural ("frivolities") to refer to specific silly acts or objects, whereas "frivolousness" is strictly an uncountable abstract noun.

Word Origin & Etymology

Formed in English from the adjective "frivolous" plus the native suffix "-ness." The root derives from the Latin "frivolus" (silly, empty, or trifling), originally related to "friare" (to crumble or rub away into small, worthless pieces).
