Semantic evolution
In Medieval Latin it meant chance or an accidental event.[4][3] In Poland it was used of an event or circumstance.[2] From the 15th century British documents also used it for casual revenue, income falling to a lord by chance, listed beside forfeitures, wardships and marriages;[3][5] in grammar Grosseteste used it for the assignment of a word to a case.[3] The English casualty, “chance, accident”, was formed separately from casual.[6]
