Etymology

It is a medieval formation from Latin cāsuālis + -tās.[1][2]

Earliest recorded meaning

Its earliest dated record in British sources is from 1330, in the Register of Hereford, where crops may be lessened by storm, accident or barrenness.[3]

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]

Timeline

  • 1349 – A charter speaks of disputes arising from certain circumstances.[2]
  • 1460 – The English Fine Rolls list casualitates among a manor's revenues.[3]
