Origin & History of “incident”
An incident is literally that which ‘befalls’. In common with accident and occident, and a wide range of other English words, from cadaver to occasion, it comes ultimately from Latin cadere ‘fall’. this was combined with the prefix in- ‘on’ to produce incidere ‘fall on’, hence ‘befall, happen to’. Its present participial stem incident- passed into English either directly or via French. The use of a word that literally means ‘fall’ to denote the concept of ‘happening’ is quite a common phenomenon. It occurs also in befall and chance, and operates in other languages than English; Welsh digwydd ‘happen’, for instance, is derived from cwyddo ‘fall’.
