That declaration pushed the firm into a category of elite contractors that get their work renewed without bidding.
By the same token, the "national Obama white vote" category, sometimes discussed these days, is skewed by the South.
The best idea for Depp, then, would be to embrace this idea that the category of “box-office star” is kaput, for him at least.
Anthos was also nominated for a James Beard Award in the category of Best New Restaurant.
Here are the facts—with important exceptions in every category.
Betteredge's present effort at corresponding with me came within this category.
The category of quantity, therefore, does not admit of variation of degree.
This might take it out of the category of crosses as a symbol of any religion of which we have knowledge.
So it is with all other contraries falling under the category of quality.
For those who commonly go by the name of the Seven Sages are not admitted into the category of the wise by fastidious critics.
1580s, from Middle French catégorie, from Late Latin categoria, from Greek kategoria "accusation, prediction, category," verbal noun from kategorein "to speak against; to accuse, assert, predicate," from kata "down to" (or perhaps "against;" see cata-) + agoreuein "to harangue, to declaim (in the assembly)," from agora "public assembly" (see agora). Original sense of "accuse" weakened to "assert, name" by the time Aristotle applied kategoria to his 10 classes of things that can be named.
category should be used by no-one who is not prepared to state (1) that he does not mean class, & (2) that he knows the difference between the two .... [Fowler]
theory
A category K is a collection of objects, obj(K), and a collection of morphisms (or "arrows"), mor(K) such that
1. Each morphism f has a "typing" on a pair of objects A, B written f:A->B. This is read 'f is a morphism from A to B'. A is the "source" or "domain" of f and B is its "target" or "co-domain".
2. There is a partial function on morphisms called composition and denoted by an infix ring symbol, o. We may form the "composite" g o f : A -> C if we have g:B->C and f:A->B.
3. This composition is associative: h o (g o f) = (h o g) o f.
4. Each object A has an identity morphism id_A:A->A associated with it. This is the identity under composition, shown by the equations
id__B o f = f = f o id__A.
In general, the morphisms between two objects need not form a set (to avoid problems with Russell's paradox). An example of a category is the collection of sets where the objects are sets and the morphisms are functions.
Sometimes the composition ring is omitted. The use of capitals for objects and lower case letters for morphisms is widespread but not universal. Variables which refer to categories themselves are usually written in a script font.
