case

The word 'case' entered Middle English around the 14th century, primarily deriving from Old French 'cas' and Latin 'casus', meaning 'a falling, happening, event, occurrence'. This Latin root itself comes from the verb 'cadere', meaning 'to fall'. Initially, it referred to an event or occurrence, closely related to the concept of chance or fortune. Over time, its meaning broadened to encompass a specific set of circumstances or a particular instance of something. The legal sense of a 'case' (a lawsuit) emerged by the late 14th century, influenced by the Latin legal term 'causa', which also related to a cause or lawsuit. The meaning of 'container' developed later, around the 15th century, likely from the idea of a container for things that have 'fallen' or been put into it, or perhaps influenced by the Old French 'casse' (box, chest). The grammatical sense of 'case' (nominative, genitive, etc.) appeared in the 16th century, stemming from the Latin grammatical term 'casus', referring to the inflection or 'falling' of a word's ending.
