Synonyms Accidental, Chance, Casual, Fortuitous, Incidental, Contingent. The first four are the words most commonly used to express occurrence without expectation or design. Accidental is the most common, and expresses that which happens outside of the regular course of events. Chance has about the same force as accidental, but it is not used predicatively. There is a tendency to desynonymize accidental and casual, so as to make the former apply to events that are of more consequence: as, an accidental fall; a casual remark. As to actual connection with the main course of events, casual is the word most opposed to incidental; the connection of what is incidental is real and necessary, but secondary: as, an incidental benefit or evil. An incidental remark is a real part of a discussion; a casual remark is not. Fortuitous is rather a learned word, not applicable in many cases where accidental or even casual could be used; perhaps through its resemblance to fortunate, it is rarely if ever used when speaking of that which is unfavorable or undesired; thus, it would not be proper to speak of a fortuitous shipwreck. It is chiefly used with the more abstract words: as, fortuitous events; a fortuitous resemblance. That which is contingent is dependent upon something else for its happening: as, his recovery is contingent upon the continuance of mild weather. See occasional.

n. Anything happening, occurring, or appearing accidentally, or as if accidentally; a casualty.
