The word "incidence" has a fascinating history. It originated in the 14th century from the Latin words "in" meaning "into" and "cidere" meaning "to fall". In Latin, the phrase "in cidere" literally meant "to fall into" or "to come across". The word "incidence" was borrowed into Middle English from Old French, and initially referred to the act of falling or occurring suddenly. Over time, the meaning of the word expanded to include the idea of happening or occurring, particularly in relation to events or circumstances. Today, the word "incidence" is used in a variety of contexts, including medicine, law, and everyday conversation, to describe the occurrence or happening of something.
