casuali

Casuale is an Italian adjective meaning accidental, fortuitous, incidental, or random, depending on context. It describes events, circumstances, or things that occur by chance rather than by design or necessity. The masculine and feminine forms share the same plural form casuali, used with plural nouns such as incidenti casuali or circostanze casuali. The adverbial form casually in Italian is casualmente, meaning by chance or coincidentally.

Etymology and usage notes: casuale derives from Latin casualis, from casus “fall, happen.” In everyday Italian, casuale conveys a sense of contingency or lack of planned intention. In statistics and probability, casuale is used to describe randomness or stochastic phenomena; for example, variabile casuale means a random variable. In more formal technical language, terms like caso (case), evento casuale (random event), or probabilità are common.

Examples and nuance: In ordinary speech, one might say “un incontro casuale” (a chance encounter) or “un errore casuale” (an accidental error). In philosophy or probability, casualità refers to the notion of contingency or fortuity, while casualmente is used for actions or events that occur by chance or coincidentally.
