fortuity

This term describes the state of being accidental or unplanned. It carries a neutral to positive connotation, often suggesting a lucky coincidence or a serendipitous event. While it shares a root with fortune, it focuses specifically on the randomness of the occurrence rather than the resulting wealth or status.

As an uncountable noun, it refers to the abstract quality of chance. It is rarely used in casual conversation, appearing instead in formal writing, legal contexts, or philosophical discussions regarding causality and randomness.
