Etymology
Origin of incident
First recorded in 1375–1425; late Middle English, from Middle French, from Medieval Latin incident- (stem of incidēns “a happening,” noun use of present participle of Latin verb incidere “to fall upon, befall”), equivalent to Latin in- in- 2 + -cid- (combining form of cad- “fall”) + -ent- -ent; see cadenza
Explanation
An incident refers to a particular happening, sometimes criminal but always noteworthy. If there was a food fight in the cafeteria, an e-mail might be sent to the parents of all students telling of the incident at school. The word incident is quite vague. It can refer to a humorous occurrence or a violent one, something that disturbed one's routine or something unusual that happened. If a child screams in a library, it's not that unusual, but if an adult does, that's an incident! As an adjective, incident is used in the field of physics to describe particles or radiation that fall on a surface. The incident light showed how dirty the windows were.
