case

case: [13] There are two distinct words case in English, both acquired via Old French from Latin and both members of very large families. Case ‘circumstance’ was borrowed from Old French cas, which in turn came from Latin cāsus ‘fall, chance’. This was formed from the base of the verb cadere ‘fall’. The progression of senses is from the concrete ‘that which falls’ to the metaphorical ‘that which befalls, that which happens (by chance)’ (and English chance is also derived ultimately from Latin cadere).

Other related words in English include accident, cadence, cadaver, cheat, chute, coincide, decadent, decay, deciduous, and occasion. Case ‘container’ comes via Old French casse from Latin capsa ‘box’, a derivative of the verb capere ‘hold’ (which is related to English heave).

At various points during its history it has produced offshoots which in English have become capsule [17], a diminutive form, cash, chassis, and perhaps capsicum [18] and chase ‘engrave’.

case (n.1)

early 13c., "what befalls one; state of affairs," from Old French cas "an event, happening, situation, quarrel, trial," from Latin casus "a chance, occasion, opportunity; accident, mishap," literally "a falling," from cas-, past participle stem of cadere "to fall, sink, settle down, decline, perish" (used widely: of the setting of heavenly bodies, the fall of Troy, suicides), from PIE root *kad- "to lay out, fall or make fall, yield, break up" (cognates: Sanskrit sad- "to fall down," Armenian chacnum "to fall, become low," perhaps also Middle Irish casar "hail, lightning"). The notion being "that which falls" as "that which happens" (compare befall).

Meaning "instance, example" is from c. 1300. Meaning "actual state of affairs" is from c. 1400. Given widespread extended and transferred senses in English in law (16c.), medicine (18c.), etc.; the grammatical sense (late 14c.) was in Latin. U.S. slang meaning "person" is from 1848. In case "in the event" is recorded from mid-14c. Case history is from 1879, originally medical; case study "study of a particular case" is from 1879, originally legal.

case (n.2)

"receptacle," early 14c., from Anglo-French and Old North French casse (Old French chasse "case, reliquary;" Modern French châsse), from Latin capsa "box, repository" (especially for books), from capere "to take, hold" (see capable).

Meaning "outer protective covering" is from late 14c. Also used from 1660s with a sense "frame" (as in staircase, casement). Artillery sense is from 1660s, from case-shot "small projectiles put in cases" (1620s). Its application in the printing trade (first recorded 1580s) to the two trays where compositors keep their types in separate compartments for easy access led to upper-case letter for a capital (1862) and lower-case for small letters.

"The cases, or receptacles, for the type, which are always in pairs, and termed the 'upper' and the 'lower,' are formed of two oblong wooden frames, divided into compartments or boxes of different dimensions, the upper case containing ninety-eight and the lower fifty-four. In the upper case are placed the capital, small capital, and accented letters, also figures, signs f
