Here the printer's tray has become a property of the letter itself. A letter's case is whether it is a capital or a small letter, named for the printer's type tray where each kind was stored. The word now applies to text in any alphabet with capital and small forms, so a style guide can fix the case of a heading and software can match or ignore case.

Latin marks the subject of a sentence with the nominative case.
Many languages use the genitive case to show possession.
UsageNamed with an adjective first: the nominative case, the genitive case.
Note
Grammarians treat a case as something a word receives from its position: the subject of an indicative or subjunctive clause "is always assigned Nominative case," as Andrew Radford puts it in 1988. In English the difference surfaces in pronouns, where they, not them or their, fills that subject slot.

Beverage suppliers report volume by the case, with one case set at 192 fluid ounces.
The cola maker's U.S. volume grew to two billion standard cases, counting fountain syrup as well as bottles and cans.
Note
An accounting unit rather than a box. In US beverage sales, fixing a case at 192 fluid ounces lets volumes be compared whatever the containers. A sales case therefore need not match any carton on a shelf, including the box of identical items. Treat it as American trade jargon and explain it when writing for a general audience.

- 16In a switch statement, a block of code that defines one of the possible actions.
The default case runs when no other value matches.
Add a new case for each menu option the user can pick.
Note
In a C-style switch statement each case is a labeled branch, and the trap is that control does not stop when a branch ends. "Execution does not automatically stop at the next case," Stephen Prata warns in C++ Primer Plus. Programmers therefore usually end each one with a break statement to prevent case fall-through, the term for running on into the next branch.

I thought it only an amourette when you told me. It was a fire — a conflagration; subdue it. I saw it was a case, and I advised you to try — dissipation.
1876, The New York Drama, volumes 1-2Poor fellow, just as I thought! It's a case with him, anybody can see that. He is thinking about Christine, for a certainty. Lovers always take to stargazing and moonlight dreaming — it's part of their complaint.
1867, The Young Ladies' JournalNote
Nineteenth-century talk for being smitten. "It's a case with him," says a speaker in The Young Ladies' Journal of 1867, reading the signs in a lovesick man's stargazing as "part of their complaint." A play collected in The New York Drama (1876) sets a case against a mere amourette: it was "a fire" and even "a conflagration." Today it reads as period dialogue.

- 19A shallow tray divided into compartments for holding metal type, traditionally paired as an upper tray for capitals and a lower one for small letters.
The compositor picked type from the case, drawing capitals from the upper section.
An old printing case sat in the museum, its compartments still labeled.
Note
A compositor's word from the age of hand-set metal type, and the root of two phrases still in daily use. The trays came in pairs: the upper case held capitals, small capitals and accented letters, while the lower case held small letters, figures, punctuation, and the quadrats and spaces that fill out a line. From that pair comes the capital-or-small distinction for letters themselves.

- 20In poker, a hand of four cards of the same rank; four of a kind.
Note
Card-table slang for holding every card of one rank: a case of aces is all four aces. Use it among poker players; in general writing, four of a kind is clearer. The same table uses the last-card adjective for the single card of a rank still unseen, so context decides which is meant.

Note
An adjective that stands directly before the rank: the case eight, the case ace. Poker players reach for it when counting outs, as David Apostolico does in 2006, listing "the case ace, two nines, and three tens." Because it means the only one left, it has no comparative; no card can be more case than another.

- 23A counterfeit crown: a fraudulent five-shilling coin passed off as genuine.
The price of a case (five shillings piece bad) from the smasher is about one shilling; an alderman (two and sixpence) about sixpence; a peg (shilling) about threepence; a downer or sprat (sixpence) about twopence.
1859, Snowden's magistrates assistantNote
Criminal slang from nineteenth-century Britain for a bad five-shilling piece. The 1859 edition of Snowden's Magistrates Assistant prices it like stock: a case cost about a shilling "from the smasher." The same price list names an alderman (two and sixpence), a peg (a shilling) and a downer or sprat (sixpence). The word belongs only in historical writing.
