Late Middle English (in sense 2 of the adjective and sense 3 of the adjective): from Old French casuel and Latin casualis, from casus 'fall' (compare with case1).

  • case from Middle English:

    Case ‘an instance’ is something that happens or befalls, coming via French from Latin casus ‘a fall’, also the source of casual (Late Middle English). The case meaning ‘container’ is from Old French casse, the modern forms of which is caisse ‘trunk, chest’, based on Latin capsa, related to capere ‘to hold’ ( see capable). Latin capsa is also the base of late Middle English capsule, a general term at first for ‘a small container’, and cash (late 16th century) originally meaning ‘money-box’. The same base gave rise to late Middle English casement, which was first recorded as an architectural term for a hollow moulding.
